What is the best Game you've played and which one was the worsed? And why? As for myself, I'd say that the Portal series are the best games I played so far. I just love the atmosphere of kinda being controlled by an artificial intelligence. The worst game, for me, is Pokémon Rumble U or many mobile Apps. Pokémon Rumble U is good (I think), but I don't like the concept of the game(Or whole series). It's "just" button smashing and ,personally, I don't like that.
