Another good thing about the PS3 is that you have access to all the Playstation Network games if you want to go back and pick up the older Final Fantasy games. And you don't need anything extra in order to get it online. (Correct me, if I'm wrong but I think you need to buy a $70 wireless connector in order to give it wifi capabilities). We have both the PS3 and the Xbox but it seems like we end up using the PS3 over the Xbox for pretty much everything.

Good luck with your decision!
