im already for sure getting halo 4, but cant decide between these two.If you have played every AC game then AC3 for sure. If you haven't you probably won't understand some parts and it won't be as enjoyable so Dishonored might be a better choice.
Go for Dishonored if you want a slick style of killing using super powers, if not, go for Assassin's Creed 3. Better if you can buy them both because they are both good games.Assassin's creed 3. If you have played through all of them, this game will be amazing, and if not, you can just read the plots of the other games on wiki or something. Dishonored...i dont think its going to be that great of a game, but thats just me.
Dishonored. Dishonored looks good and it is definitely doing a ton of creative things, especially being FPS which is a major turn-off in general.
Assassin's creed 3 will be released on October 30, 2012.
