Ah ED...
It's potentially the best game I won't ever recommend to anyone. I have a personal love and hate relationship with it. I've been into those open space trading games for a while now, starting with Frontier Elite 2, then Privateer, and both sequels (FFE, it's amazing new graphics and its even more amazing bugs, and Privateer 2, of which the least said, the better). ED, when announced, was half-way to the dream. I wanted a modern FE2/FFE. Something with realistic systems, distances, and newtonian flight. I wanted time compression too so that even though you compress the actual cruise, in-game time blazes through, reinforcing the message that it's a very very big place you're moving through. Of course, ED was only part of that, with the modern tech ticked, but not the rest, since it was seemingly all about multiplayer, and therefore a stupid constant deathmatch and ridiculous travel times due to the impossibility of time compression in a multiplayer setting. There was one bright hope though: Braben promised a full offline mode, with the caveat that people playing with it wouldn't get to "enjoy" the wonders of a dynamic galaxy shaped by gamers. If that was a downside, I'm the Pope. And offline mode meant mods, whether Frontier liked it or not. There was a chance there that anyone could actually turn ED into the game they wanted. Of course, the story was predictable enough, and a few weeks before release, the offline mode got canned. That pissed me off so much I didn't even bother creating a character at launch. Thikn it took me 3 to 6 months before finding the motivation to visit the game...
Anyhow, the game is very much more of an Elite 1 than anything. Flight, both in normal space and in 'hypercruise' obeys to gamey physics (speed limits in space, gimped yaw axis to make combats 'more interesting', magic throttle zone that makes you turn faster, etc), and the game loop is the same: trade/kill and make credits. Rinse and repeat. And you do that with an incredibly boring navigation system: there's pretty much nothing to do. 99.9999% of the mechanical 'challenge' if you can call it that is taking off and landing in stations. The rest is watching paint dry as timers count down to jump away, leave hypercruise or enter hypercruise.
In terms of environment, it does that stuff rather well though. The game is absolutely gorgeous, and with planet surfaces and a deployable buggy, it's very much a dream come true, as that sense of scale is on point. Game-wise, it's absolutely pointless apart from shooting random rocks for semi-random materials for semi-random upgrades. But honestly, I could have lived with absolutely useless surfaces, so their stupid gamification doesn't impact me much, apart from the fact that they felt they had to add a shitload of stupid random pointless small bases with hostile drones. Meh.
The soundscape is ok, although a bit awkward. Now that's not general opinion: the consensus seems to be that the soundscape is amazing. I'm just the weirdo here. First there shouldn't be any medium for sound to travel in space. So they came up with the idea that the computer simulates it for your own awareness. Cool, that makes complete sense, and I'd be delighted with that actually if it was well implemented. However this is only an excuse, as the game simply has sound in space. Take something you can't see on sensors, and their sound will still echo through your ship. Ooops. Then they made a point that when your canopy breaks (because of course, in an age of cameras and sensors, ships still fly with a giant glass window at the front), there is no more sound. Allegedly this is because there is no more air in your cabin to convey the sound. I guess there's no air anymore either in your flight suit then. And that headphone technology is a mysterious forgotten tech... It may not sound like much, but this is the template for the entire game design. Everything is ad hoc and gamey, with an afterthought excuse afterwards to explain in technobabble why it's totally realistic. And it never checks out. Thing is, FE2/FFE, with all their gamey aspects and limitations, have spoiled me with the Elite franchise, and I was expecting them to go more towards semi-realistic exploration of the space age, not to regress towards arcade with pretty excuses.
Still, it's enjoyable as a game. The arcade combat has a good variety of equipment, and the 6-DoF controls make for some interesting flight patterns. Of course, the point of combat, apart from making credits, is dubious. Like, every system has a 'Nav Beacon' around the surrounding star. Unless you're totally flying in the dark with no system map and no sensors, there are absolutely no reason to get out of hypercruise to normal space around that beacon. Yet, if you do so, you'll encounter lots of trading ships, police ships, and outlaws of different factions. All are there just so that you can find them and shoot them. They have no reason at all to be there apart from being shooting gallery targets. Same goes with mining rings, illegal stations, etc. There is almost no reason whatsoever for all those outlaws and traders to just normal cruise there, but then you wouldn't have anything to pew pew, so they're here, like idiots.
In fact, it's the entire universe that makes zero sense. Crime makes no sense, since people apparently respawn in this universe. Well, the official excuse is that you're in an escape capsule with a special hyperdrive engine. Cool. You're at the other end of the galaxy and that escape capsule gets you back to Earth in a half-second. Why don't they fit escape capsule engines to ships then? Piracy makes even less sense, as the effort, time and criminal bounty involved in doing it are absolutely ridiculous and insanely tiny compared to what you could make in 5 minutes of hauling a cargo of shit (literally) from an industrial station to an agricultural one. Also, the pirating ship is probably worth 27364 times the stuff it's trying to steal. So, well, there's meaningful trade at least. Or is there? Well no. With the stupid multiplayer focus, there's zero meaningful trade. Check your in-game clock and travel between planets. It takes like 5 minutes to go from planet A to planet B 100LY away. Yet, somehow, there are constant planetary-level crisis such as famine or iron shortages. It's like my neighbour dying from hunger and offerring me €50000 if I could just drive or cycle to the corner store 2 minutes away to get him a box of cereals. The economy makes absolutely no sense. It's just like NPCs, it's only there so that players can abuse it.
So, I'm ranting a lot because I had big hopes for that game and a lot of them have been crushed by the stupid multiplayer focus (well of course, if the game wasn't online-only, they couldn't make cash selling ship skins, so...). But what's left? I still have something like 600h on record, so the game does something right. Well, to me, it's the immersion. The game does look absolutely magnificent, and the inside of stations and planetary landscapes are gorgeous. It means that in my own Mind Theatre (tm), I can rp myself as someone pretending to do stuff, and enjoy the surroundings in the meantime. I've also travelled to the centre of the galaxy early one, just because I was sick of the stupid pew pew that was the inhabited bubble, and it was cool, although lonely, to just jump from system to system and take in the sights. 'Exploration' is a bad word and 'Sightseeing' would be more accurate to what you do then, but it was cool and I enjoyed it for a few months. After a while, you've seen most of it, but still. If they added an option to walk around my ship and on stations, even as a meaningless feature devoid of their stupid minigame approach to content, I'd be in heaven.
Right now, I've been on an extended break. Fired up the game again last week after over a year of not touching it, flew to my old favourite Prison System (which of course has been turned into a liberal democracy by players now), did a passenger transport mission, and well, it's still as pretty as ever, and it was great to feel aboard my slug of a Dropship again. I have to give a go at the revamped mining to see what it's like. Ice mining used to be a favourite of mine before: nothing exciting, and mechanically naive, but the loneliness and pretty sights made it a zen activity. Couldn't care less about the payoffs since I've got hundreds of millions of credits I'll probably never use already, but ah, the experience was neat.
So, in conclusion, I'd say that on sale it's probably a very safe game to pick if you're into space trading games in the first place. You're likely to spend a good 15-30h just discovering everything that's there. From there, you'll have seen it all and it's just about doing the same things over and over. So you might be bored to tears and leave, but that should have made the sale price ok. Or you might be a bit awkward and ask for more, in which case, well, there's no sub fee, so you can dive in and out whenever you feel like it with no remorse. I'd absolutely pick up the Horizons expansion though, as it gates planetary landings, and they're a massive part of the atmosphere imho. Also, it gates 'Engineers' aka RNG-rolls-to-make-your-stuff-better-and-ensure-PvP-requires-a-massive-grind-before-you-can-compete.
