Re: Whats your favourite PES/WE title?
PES 6, although bear in mind most of reasons below apply to PES 5 too. It's just matter of preference. If PES 6 wasn't an option, then probably I would vote for PES 5 which I've played for few months on PS2 between 2006 and 2007 and good lord was it a joy. Also I have to give honourable mention to PES 2013, while I can't get into it, many of my friends did and I can see why. There is definitely something decent about this game.
Anyway, PES 6:
1.) It remains by far most complete football game in PES series. Everything that's supposed to be in football game is there. Period. You might argue about eight directions - fine, pass assistance - fine, but whoever came up with this designs had clear vision how to make them, and actually made them right. Made them WORK which becomes less and less obvious with more modern games, not only PES. Some features might be simple, some underwhelming, but at least they work as intended.
I do not have time nor money to support
maybe next year they will get it right or
base is there now they will build upon it. No. Games, just like about any products manufactured by any company on this planet are supposed to be finished. Simple, but finished.
PES 6 is finished. Somebody started making this game, went through the process and completed it.
2.) Modders in general that vastly extended and IMHO turned this game from great to immortal. For example I've heard you guys are bored of Master League with three stadiums, hahaha xddddddddd, I have no such problem

Not to mention modders version of PES 6 online server and online roster tools. I've managed to set up my own private PES 6 server in like twenty minutes. No input lags, connections lost, establishing communications, lag cheaters, no-lag cheaters, it's unbelievable. You can actually play the game, with no issues whatsoever, which is amazing for long unsupported title which has its servers turned off for years.
3.) Gameplay, which remains incredibly balanced and provides great fun despite many simple designs. All in all it is a game, it's supposed to simply be fun. And game puts a player through a test of his skills, not only in button-pressing but also thinking department. Naturally sooner or later anyone will overcome AI, it's just a nature of things. Online matches with my friends were some of the best gaming experiences ever. Football game does not have to be complicated - I honestly laugh at all "football simulators" and stuff, there are so many things to consider when simulating something I can safely say neither PES nor FIFA will ever reach level of simulation. Immersion and fun come from great balance of all gameplay elements, not some sort of overblown "simulator" factor.
TL;DR: Incredibly polished, supported by modders for a decade, greatly balanced football game. Not a simulation, not at all, just amazingly crafted piece of a computer game. Easy as that.
