Here is my updated feedback that I posted in the Steam forums after completing the Denmark Campaign and getting about halfway through the available Britain content.
This is the last day where I have the time to contribute to the beta (I think), so I thought I'd write up an overall feedback post.
Usability:
The most annoying thing in the game to me is the lack of functionality of the area map. The full rotating camera combined with not being able to use the area map to jump to location is quite annoying and it means you have to constantly pan the camera around all the time to navigate the areas.
I think this would be less bad if you could use the area map to center the camera in the area by double clicking on the area map like you could in Baldur's Gate & similar games.
Another thing that would be nice is a hotkey to center on the party as when you're off looking for something, you have to manually scroll back (I think).
It would be nice to have some options in the Graphics menu to disable post-processing effects, particularly stuff like Bloom (as I find that a bit annoying).
The only other thing I can think of is maybe have a tooltip on the area map that tells people how to move the area map around. After you do the forest outside Skejn and the Farm, the next area is off-screen and it took me a little bit to realize that the map was actually bigger than it was. Coming from a Baldur's Gate player that's pretty noob of me though.
Otherwise I think usability is pretty good. There's not really anything else that blatantly sticks out as being annoying when interacting with the game.
Combat:
I think Combat is too lethal compared to Expeditions: Conquistador. It's too easy to kill people in one hit, and most enemies (and even party members) can be felled by one or two strikes very early on in the game.
From memory (I would A/B test if I had time but I don't), it was more likely for you to kill enemies in 3-4 hits in Conquistador, with the odd 2 if you got a crit. In Viking it seems like you get one-shots pretty often, particularly if you have a unique weapon.
I made an Archer and found a unique bow and I also found a Unique spear pretty early on that I gave to Nefja and those two characters one shot people very often. It's super easy as an archer to take out an enemy with a Signal Arrow > Quick Shot combo, as it often raises the hit chance to 95% from considerable distances. It's very easy with Aimed Shot or the above combo to almost never miss compared to Conquistador. It's *way* too easy to get 95% chance to hit as an Archer
Personally I think the damage balance in Conquistador was better, and ranged accuracy should probably be lowered a bit.
I remember reading that shields will be getting a buff, particularly against Archers, but I don't think that will solve the issue (if you see it as an issue).
I think armors could be given a bump in protection, and maybe overall damage from weapon skills toned down a little?
The AI is also not great at the moment but I know that improvements will be coming, so I don't really see the need to talk about that.
I'm also finding the combat way too easy on Insane difficulty. It is possible that a fully implemented camping system and AI fixes will solve the issue.
The map style is very different from conquistador, it seems like there's a lot less emphasis on use of choke points at the moment, and it's more about moving from cover point to cover point and getting some picks with Archers before moving in with melee for the mop up. I have only had to use items once or twice in the very first few fights in the game and then I haven't used a single item since. In Conquistador you needed to use items because enemy numbers were high. I haven't seen that many encounters with heaps of enemies in Viking so far, so I haven't needed to use items to even the odds. Enemies also prefer to hide behind cover instead of push as well.
There could be some more traps in the setpiece fights - I think I've seen one net trap in the entire game so far. Enemies don't use items either (but I'm sure you're aware of that).
Character Progression:
Character Progression seems a bit off at the moment. I think this has previously been discussed but I went for the weapon skills first, which pretty much trivialized all combat. Once you get like Rank 4 in any weapon skill, combat becomes an absolute breeze. I think one of the devs was talking about capping weapon skill progression ranks until you've gained X amount of points and I think that might be a good way to go.
So far in the game (I'm probably half way through the available Britain content), I've found one unique item of every weapon type except one-handed axes. Perhaps I missed it?
Swords seem to be a little bit underpowered. The Offensive Skill tree is mostly good but aside from characters already having assigned Cripple and Anticipate Opening at the beginning, I'd probably never pick those in the future. Cripple seems a bit redundant at the moment because if you're melee, enemies usually won't move if you're next to them (and you kinda have to be to use Cripple) and if you're Ranged you can most likely kill the target in one turn anyway.
Anticipate Opening doesn't seem worth losing an attack action over. Make two normal attacks to deal 1x[x2] damage to do 1.05-1.5x damage on the next turn ? No thanks.
Mostly every other skill seems ok, except for Sharpshooter. Raise the minimum ranged accuracy from 5% to 10%? Haha, most of the time I have over 80% chance to hit. At the moment that's a complete waste.
In Conquistador I picked that one, because in a lot of encounters you were actually quite a fair distance from the enemies and the hit chance was a lot lower, so it was worth it for RNG pot shots. In Viking it's not worth it. Opportunist also doesn't seem worth it because I've never seen enemies potentially provoke 2 AoOs from the same character in a turn.
Denmark Content:
I thought the Denmark content was pretty good. Nothing groundbreaking. Pretty straight forward dialogue and simple quests, similar to Conquistador really - the main change being how you explore the world. The 'flow and experience' was fine to me. I think it will be better with more world map events and proper camping.
The main thing that bothered me was that companions were pretty quiet after you recruit them. In Conquistador they were more of a part of the game outside of combat due to the CYOA screens and they often interjected more in quest dialogue.
I wasn't really that big on having to recruit the 3 extra random mercenaries that you create at the end of the campaign. It would be better if you could get characters from Skejn instead but it's not too big of a deal. I can kind of see how you might need the extra people to simply cover camping mechanics, but I don't think it's quite as good as in Conquistador where you probably had your Scholars and different types of not necessarily combat oriented people that added a bit of flavour to the journey and also were part of the CYOA stuff.
Britain Content:
I haven't finished it yet, the content that I've done so far has been fine other than basically no reactivity from Morcant as I'm killing his people ... unless he's meant to be like that. Went in and killed the guys in that Church, didn't say a peep.
Overall Content Remarks:
There could be more hand placed loot, particularly in the tucked away containers on maps. Feels more rewarding to find something specific that was "hard" to find.
I'd suggest making more use of 'small' containers, like seeing the small highlight of pixels on a table and picking up some valuables, or a dagger in a body that you can pick out of the body. It just feels nifty, as close as you can get to 'secret'/hidden items, I suppose.
There were no pickable herbs in York that I remember, which seems odd.
The Swamp area could use a container/consumable pass.
And performance could be improved. I average 40-80 FPS on my i7 4790K / 16GB RAM / HD7970 OC Windows 7 machine, and my video card fan is very loud when playing. In other Unity games I've generally gotten ~100 FPS or more on average. The areas are pretty though, but Unity games are generally CPU-bound, so...
Hopefully that's helpful. I'll continue playing today and maybe update my Britain Content feedback.
EDIT: By the way for those reading out of interest, so far I've found that there is less combat than in Conquistador. You spend a lot of time in Conquistador fighting random encounters on the worldmap. Here it's mostly set fights in areas.
