I played the demo.
From the demo and the quicklook, it seems this game is made for co-op play, wich is fine.
I'm more of a solo player, though. Is the game playable solo? In the demo, it seemed like it would be pretty hard for a solo player to be able to manage everything. I'm going to try Orc must die, also, but I prefer the style of Dungeon Defenders, and I envoy game with loot. I can enjoy co-op centric game even if I play solo (I loved Boderlands) but the issue here is more about the difficulty.
I don't mean to bash the game or anything, it seems pretty cool. I just don't enjoy multiplayer. Does someone plays the game solo here? Is it still fun?
