which cheap game should i get

i want to get a new (used) cheap game and i want to pick from Assassin's Creed, Rainbow Six : Vegas 2, and Prince of Persia.

So which one do you guys recomend~please tell me why

Or if you no of any other cheap used game, please tell me :D

USA

Assassin creed this is the best game take it and have a fun with it;)

My favorite of those 3 is Prince of Persia and I've played them all. This is just my opinion. For me it goes 1. Prince of Persia 2. RSV2 3. Assassins Creed.

Bioshock. Just because I said so.

My first pick would be assasin's creed. It wasn't the best game, but it was pretty fun running around in that game, just watch out for the beggers.

if you dont already have bioshock get that but out of that list assassin's creed just because it has a really good looking sequal coming out later this year

R6V2 especially if you are going to play co-op. Very fun that way. Stay away from AC as the gameplay is just very repetitive and in my opinion one of the worst games you can play.
