I'd say AC wins, because I much rather the open-world experience compared to Prince of Persia's linear style. I'm not a big fan of PoP's combat system, just because button mashing isn't really my thing.
I think assasin's creed is better, because prince of persia is pretty much the same al the time.. Assasin's creed has more variation and has a better story
the original PoP triology was better but now because of ubisofts retarded decision to make the prince of persia have look a lot worse and little shitty magic made everyone think its terd today. but any one who hasnt played the original triology, play them their awesome. AC is really good but the original PoP was the best
People,people,how could you compare this games.Assassin`s Creed is lika a Role Playing Game and Prince of Persia is not,they aren`t the same kind of game.Prince of Persia is based only in continuous stages of missions and Assassin`s Creed let`s you free to go into the the town,so people don`t compare thoese games.But in every case Assassin`s Creed it`s way better.
