It's a nice game, but was only 2 acts when I played it. I hope they've added some more content to the game considering it was quite short before. Getting a group and playing would probably be quite fun. I mostly played 2p with Lezard, but had a night with 4 player as well (Schmacko and Chase as well). Classes are nice, planning a build from the tree is also great, since there's tons of possibilities. Played quite a lot of D2 back in the day, and comparing them, PoE is quite the good game.
Think I'm gonna try it out a bit again.
