That PES 5 with Henry & Terry on the cover was my GOAT football game period.
I spent countless hours just fukking around editing on that, making my own football team that I played for but since it moved to 360 & PS3 it fell off more than anything I know. It's kinda sad how now there's only a select few people who are still really pushing for PES I remember converting my friends to PES 6 but since that it's been FIFA all the way and I don't even like FIFA like that, infact FIFA career mode is straight boring to me.
Licenses have never been a big issue for me on PES and it's even less of an issue now you can download Option Files that PES geeks make to have all the kits & names fully licensed but it is what it is and like someone else said PES has just stagnated on the next gen and FIFA has really clawed back a lot of it's market share.
I doubt I will buy either but if I did it would probably be FIFA b/c that's what all my friends are playing and essentially with games like this it's always going to be a decider what your friends are playing.
Unreleated note Football Manager is the GOAT Football Sim game, just know that.
It's the reason I don't care for PES or FIFA
