1) The main thing Id like to know is, does the AI cheat to win games as much as FIFA? Cheating in FIFA has become brutally obvious and even though I still have a decent record, it literally kills the game for me.
-To be honest, rubberbanding AI is in every sports game in my opinion, although majority of the time, late AI goals in games can be avoided by playing composed possession, especially if you're leading by 1. Back on topic, PES, well to be honest, I haven't seen much cheating by the AI, maybe because the keepers, for human and AI most of the time are pretty bad(more on that later) in general, conceding goals late, for human and AI, is no surprise.
2) Is there still a patch or option file download available for PC users? That used to be the best back in the day, getting all the updated rosters and kits.
Yes, there are quite a few websites out there, pesedit, pro evo web etc. The user created kits are better than FIFA's.
3) How enjoyable is this game overall? How satisfied are you to keep playing through multiple seasons in a career?
On a scale of 1-10, I would say 6, just too many bugs that are gamebreakers. I won't mention them all, but off the top of my head: slow defenders catching up to fast players on a breakaway, keepers are terrible like previous editions, that is, can't save anything within the box, save anything longshot outside the box, input lag, and oh, did I mention bad keepers?

Regarding career mode, I haven't spend much time on it(I haven't spend much on PES in general, heck), but I take it that it also suffers from the same gameplay letdowns.
4) How are the controls and moves? Are they realistic?
This year has more of an NBA 2k-esque feel(if you play 2k basketball, you know what I mean), you don't have total control, and sometimes animations take over and do things you don't intend to do, but player movement and passing animations are pretty good, this was probably one of the few positives to me.
So all in all, if there are cheap used copies at a Gamestop and you're really curious, I would recommend getting it, but because of poor patch support and consistent lack of improvement from Konami, I really couldn't justify purchasing the game full price. Hope this post helped!
