I've been playing PES2010 non-stop since I got it, and it's great. It's a huge improvement over 2009, which was also a huge improvement over the shitty 2008. There are things to fix still (GOALKEEPERS, KONAMI!!!!!), but overall it's getting close to that perfect feel PES4 and PES5 had, the ball physics are perfect, the graphics are excellent (animations need a bit work), and the game just plays great. And of course, mods in PC version mean I already have every team licensed, the Bundesliga included, and every player corrected
Also, the Master League received a HUGE overhaul, I can safely say it's simply amazing, now it works like a real season should, and the UCL/Europa League integration to the ML is simply astounding
I'd play FIFA too, but since EA refuses to do a decent port to PC unlike Konami who care about giving the PC the same treatment as next-gen consoles, I'll have to skip it. Fifa09 was bad enough on PC already
