Hey dude! This was a very comprehensive criticism, but I'd like to add a little bit onto that, if it's alright with you!
1. The actual reccomended party size in DnD 5e is 3-5 players, with 4 players falling smack-dab in the middle of that. As a 5e DM who has been playing for, what, 5 years now, most of my parties have been in that range.
2. There will be more NPC companions coming as time goes on, at least 3 that we know of, possibly more.
3. Yeah hopefully some of the performance issues you've been experiencing will be optimized as Early Access goes along.
4. Can't say I understand *exactly* what you're saying here, but there are already very fleshed-out companion relationships, and hopefully they will become more fleshed out as time goes on and more are added.
5. That's on the "To-Be-Added-As-EA-Goes-Along checklist."
6. A lot of it relies on exploration to some extent, which I really like! If there's anything that is particularly hard to find, there should be a marker.
7. Yeah perception and trapfinding is pretty bogus right now. Hopefully to be fixed as time goes on.
8.I mean, this game already has a bunch of romance options. All of your companions and an NPC are available if you want to.
9. Larian has said they want to stay a bit further away from alignment, which is fine IMO.
10. I heard around that they're working on something like this.
11. I agree that I would like some more interaction between the companions. We have some of that with the banters, but I would very much so appreciate some small scenes or ambient dialogues at camp.
12. There actually is a system for this! If you give them some stuff for free, you can get a discount, and if you get caught doing crimes around them, they increase their prices.
13. While not fully open, I'd say that the world is yours to explore. I personally prefer the more focused design things have. Also severely doubt they're gonna rework the whole of the first act. Certain things might be reworked, but I doubt it'll be changed *that* much
14. Again, probably just EA jank.
15. That'd be nice, would like that. Possibly this will come into place when we reach somewhere civilized instead of squatting in the woods like we currently are.
16. This story seems a bit more small-scale on that front, but if you want a game like that, I would check out Pathfinder: Kingmaker and the upcoming Wrath of the Righteous by Owlcat games. Perhaps more of this will come as time goes on, but I don't think it's super plausible right now.
17. I'm cool with the amount of side quests right now, but a few more would be quite nice, I agree.
18. Common suggestion, I hope so too.
