Some impressions after having finished CS3 (spoilers included):
-I didn't expect it to take me longer to beat than 2, but it did, despite my liberal use of the speed-up options. Thankfully the game retains a high level of quality right up to the epic final boss gauntlet.
-Despite being longer than 2, I thought the pacing was better. The start is much stronger (I liked the Ymir start in 2, but the reunion with Class VII dragged on a bit too much for my taste), the middle section is suitably exploratory while having the best content in the game, and the ending doesn't drag as much as it does in 1 or 2: once the campaign and story reach peak momentum the game just rushes to its climatic ending, as it should be. To be fair to 2, in its case there were extenuating circumstances, such as the fact that there was no other section of the story where they could have comfortably stuck the Lloyd chapter and the fact that the "true" finale was essentially a post-game dungeon, but CS1 does just drag its ending out.
-The cities and regions are great. Both Crossbell and Ordis-Raquel were very well done. Great music, very cozy atmosphere, distinct aesthetics that nevertheless fit the setting well, plus plenty of content and solid overland exploration in the surrounding areas. There is even some incentive to check out the smaller shops for unique items (such as the gifts) that aren't available elsewhere, not to mention the department stores have gear that you can't get in other shops. There are also points of interest that are not marked on your journal that have some interesting stuff or contribute AP. Overall, it feels like non-dungeon exploration is a massive upgrade over the previous two games, which makes the more linear structure (compared to 2) all the more of a shame.
-Dungeons also feel like an improvement. The Dark Dragon's Nest and Juno Naval Fortress are probably the best designed dungeons in the series. I also liked how they handled the huge cast by implementing parties that operate separately but coordinate in their navigation of the dungeons. Very solid mechanic that makes party building all the more interesting (if also more time consuming) while also enhancing exploration. The Keep levels also maintain a solid level of quality throughout.
-Both the combat and the party/character building retain the strengths of the previous entries while adding new stuff that makes it, if anything, more interesting. Break is a pretty good mechanic that makes encounters and tactics more varied while, incidentally, also making Earth slots more useful to physical attackers. I'm not sure that delay is as broken as it was in 2, but this time around there seems to be a lot more stuff to experiment around with, so I didn't focus as much on it as I did back in 2. I think I prefer the Brave Orders to Overdrive in 2. However, I'll admit some of this stuff is just broken, like Ash's Crazy Hunt order. Well, at least that one is not available in the final gauntlet. Domination is still busted, hehe.
-World-building and characterization seem, if anything, to be an improvement over previous games. Western Erebonia ended up being, perhaps paradoxically, even more interesting than the Eastern part. We see fewer distinct areas, but both Sutherland and Lamarre feel more detailed than the Eastern regions. This connects to the point I was making above regarding exploration. Crossbell is also great, of course, and has made me even more curious about the Crossbell games. The new Class VII is alright, none of them is as consistently annoying as the worst of CS1's main cast. They toned down the tropey anime high school drama despite returning to the academy setting. Old Class VII is more likeable than ever as well. Rean is finally a strong protagonist (he was something of a nonentity in 1 and 2 tbh), insufferable characters like Machias are tolerable now, and bland characters like Gaius are actually cool now.
To be fair, this game benefits massively from a lot of setups from previous games that add a lot to what we see, thanks to the fact that the devs were committed from the get-go to crafting a meticulously interconnected world.
-I'm not a huge fan of the fact that they've moving away from factional and international politics and further towards "Dark Dragon" and "Ancient Evil" shenanigans, but whatcha gonna do? This sort of thing was baked into the setting from the beginning as far as I can tell (e.g. the Sept-Terrion as a motivation for Ouroboros), so I guess they have no choice but to incorporate it into things despite the fact that Erebonian politics are probably more interesting than that stuff. Not to mention this kind of thing is to be expected in a JRPG. Still, I have to admit the timing for this shift in gears wasn't the best: things were just starting to get interesting with the Calvard special forces story. Would have liked to see a bit more of that.
Not a fan of having another cliffhanger ending either, though I sorta saw it coming (I figured they'd repeat the structure of 1 and 2 with 3 and 4) and I plan on getting 4 when it comes out for the Switch in any case.
Overall, I liked CS3 a lot. Right now, it's probably my favorite in the series along with 2. I'm not sure of which I'd rank higher, they both have their strengths and weaknesses. As I mentioned, I find the more open-ended structure of CS2's midgame to be an advantage over CS3, even if CS3 has overall better areas. Either way, they are both great games, and they are both among the very best JRPGs as far as I'm concerned. It's been a while since a series has hooked me like this one did. Already looking forward to the Calvard arc.
