@GBAstar- I'll be getting it for 360. After making my post here I tried to do a little research since I honestly didn't even know what PES was from the above comments. I had heard of FIFA though. That's how out of the soccer loop I am! Anyway, the research was impossible. I quit after 30 minutes because, knowing nothing about either game, I couldn't separate fanboyism from fact on either title. I didn't realize there was such an aggressive fanbase for competing soccer titles! Guess its like anything else. Good idea on looking for 11, I'll check into it.
I'm not opposed to PES I guess since it seems to have a lot of fans too. The difficulty though for me is that, it seemed as I was looking around that FIFA has consistently improved? Whereas I saw a number of competing views on PES's evolution. A lot of fans seemd to have liked earlier versions better, so I'm not even sure which year to look at for PES.
@JoeyPoley- Thanks for the numbers info. I may peak around for FIFA 11 on the super cheap while I wait for 13 to drop, then hit ebay and craigslist for deals on 12.
