Heh, yeah I have Infamous too, I enjoyed that quite alot, it reminded me of Star Wars Force Unleashed. because graphics and play style are similar.
Assasins creed 2 involves very little forced stealth (only on assasination missions where you have to follow someone to your target without drawing attention to yourself. Most of the time you just go in fists swinging, or I do atleast
), there isn't really a stealth feature, more you try to blend with the crowd or out run pursuers, or just plain kill them all till none want to follow you anymore. The game doesn't like you killing innocent people (because it's against the creed) but other than that you can do what you like, picking fights with 20 guards is fun. Disarming a full plate knight of his 2 handed battle axe & then impaling it in his head is never dull.
