Mate, i was like you, gived up on next gen PES. And i tried another year again PES 6 with Shollym 2012 patch + Shollym Gameplay 2 Option File. The game is simply amazing, the pace and rythm of the game is better than any NextGen PES and it's very veeery hard like never before.
Is my advice.
master league works?
I for some reason though PES3 and PES5 wer emuch better than Pes6.
Something about PES6 feels a bit crappy not same as PES1-5.
