I tried to download the Winning Eleven 2007 game, which is american PES6's equivalent, but i never found a working link.

I found one yesterday, but the thing is it seems that the kitserver does not support the nodvd .exe 
(i wrote here in kitserver 6 thread)
I only played a bit in training mode, not sure about any differences to PES6, my research was mixed, some wrote it has some positives vs PES6, dunno, PES is huge placebo and recency + confirmation bias lalaland
cant be bothered to play it wo kitserver tbh
Now i will try Pes 2013, same settings as 2012, no patch on 1.0 no dlc 15 min play on 4* amsterdam arena night same teams, reading in the yair gameplay mod threads was funny on 2012 and 13

ala noo 1.0 was better or nooo demo 1 or 2 was better blabla, these guys test the patches half year and do not even play the game properly only to find out thats not save the games lol, in doubt the earlier the gamecode the better

, so just test 1.0 and move on..
i could give you the link to we2007 if you want, i think i bookmarked it
ps
2013 is sooo slow, even on speed 1 wtf, need to try with other vsync method, the konami one is slow as fu
the high balls are crap in 2013, no power at all, it all feels sluggish and "smeary" to play, 2012 is more direct, cant tell that 2013 has better animations or transitions or something
i dont think thats for me, i didnt play 2013 back then, bought yes unlike 2012 but the singleplayer modes i was dissapointed fast and never touched it again
i think its either pes 3 or 4 if some cam tool comes out for it, just want a solid game that i can play from time to time wo getting annoyed by it that much xD
yes alright both games 12 and 13 are very similar tbh, players struggle to get to them flat passes and through balls, its just a smeary drag to play nothing else
edit
hmm jenkeys tool for 2014 has ref strictness slider, now this is very interesting..
but i remember 2014 being a shell regarding player individualism/stats showing on pitch, but for now this is the only newer game that interests me, maybe 2009 for the fun, i only played that online basically, totally forgot offline experience
