Yesterday I fiddled around with PES2014 PS2 after almost 10 years (Greek version - don't think it matters)
I converted and imported a Spanish OF with emblems and kits and had a few matches. The game is..different. Not as arcadey as PES2009 and PES2013 PS2 which I played a bit earlier this year, but slower which is nice. AI attacks nicely and is fouling. I finished 10 min game with PAOK vs Man City losing 0-3 with 9 fouls made from the AI, that's something that only may happen in PES2008 PS2.
There are some weird things with this game, for example the South American clubs. Only accessible in the Copa Libertadores mode, not in general frendlies or ML, players and clubs nowhere to be found in the OF editors or the edit mode. Not sure how these things work but I'm intrigued.
Players seem a bit..smaller maybe? and that gives the impression that the pitch is a tad bigger, which is nice. The ball looks a bit bigger though in comparison which may or may not bother you.
Started an ML and had a strange bug thankfully right away, after I made a couple transfers, I just had 600 million added to the bank instead of 600 thousand after a sale

Never encountered that before in any PES PS2, is it something known?
A nice change of pace but way too quirky to fully edit and mod. It's a shame it's being updated constantly but all of the patches are of extremely low quality. They have a lot of faces, yes, but the DB is a complete mess in at least 5 of them that I tried, especially outside of the bigger teams.
