Bugs and EA servers being always down will make throw your controller to the freaking wall
One major issue about this game is that EA servers are always down, at least in Fifa 12 it wont let you try to find an online game if the servers were down, this Fifa 13 lets you try to find a match but it will always come with a message "you were disconnected from the match"
To be honest I've never played a PES game before, but this year I might trade in this piece of crap to test PES 13
I'd say rent it before you buy it
