Definitely Dishonored! Played them both and Dishonored is original - feels amazing down from its physics system to its jumps and the combat feels so fluid and each battle has meaning and tension! Graphics on both are amazing - Dishonored is a lil better - plus it has amazing style - the guys who did the art for Bioshock 2 made this game. AC3 seems to have more glitches as well - play both if you can but Dishonored deserves all the attention is can get- its a beautiful , wonderful title!
I really enjoyed AC3. I beat it a long time ago and i still play it a lot. The addition of hunting made it really fun too!
Assassins creed 3 did kick ass. The online is SO fun to track people down and to roof kills and shit. An even after you beat it, there's so much to do on the single player. Dishonered is in it's way from gamefly now, can't wait. AC3 was really meaningful tho
ac3 dishonored sucks balls, shittiest assassin game ever "don't kill too many people or you'll get a bad ending (all the endings suck, dont worry)! so here's like two weapons you can use that DONT kill for the whole game, haha have fun fucker" - makers of dishonored
