I agree mostly with what Litmanen says but his posts confidently exude cuckiness.
Anyway, are any of the expansions good? Watched some video where the guy complained they are mostly linear adventrues with no real dialogue options and dumb end-game decissions. Surely, the base game will be enough for me to get the jist of this, right?
Try the base game, if you like it, the expansions have more campaigns, but imo one of the best reasons to get them is for the additional character options (classes, mostly, but races are added too) and compatibility with all of the modded quests.
No idea about co-op.
