Assuming its single player, i tried:
-DA O, DA expansion, DA2
-Mass effect 1 2 3
-Tried witcher 1 and 2
-Morrowind oblivion skyrim
-fable 3 and reckoning KoA
i played assassins creed 2 and didnt enjoyed it at all so no assassins creed.
I prefer action and adventure and rpg combined but now it doesnt matter. AN example can be Dark souls, but its on console and i am on PC, although the PC version is coming soon.
What i only want is a game that you can only control yourself(not party, like dragon age or baldurs gate).
Some games that i considered: Bioshock infinite(2013), crysis 1 warhead and 2, guildwars 2(the only MMORPG that i considered). Any others that are a must play?
