It's not my kinda game either. I liked Witcher 1 but it was slowww and clunky. Witcher 2 was a big WTF because it started like a Michael Bay movie, the inventory was mess and combat was chaotic. W3 I'm simply not interested anymore, I don't care how big the game world is, size is not proportional to fun.
Deus Ex (2000) - a game that pushes the boundaries of what the video game medium is capable of to a degree unmatched to this very day.
