Cold hard facts are that Konami, post Seabass era, have never known how to develop a football game, never.
From the horrendous clunky UI, right down to the poor fonts, and awful colour schemes they use, to the illegible Japanglish text in game, ridiculous scripted robotic commentary, and lack of any effort with regards to presentation within the game, yet despite all the failings, underneath was always a spattering of something magical game play wise.
It took the community, largely a bunch of passionate fans, amateur coders and people willing to learn and invest time into making Konami's game the game that it was, without option files with full kits and badges, and pc mods with a plethora of amazing tweaks to make the game look 1000 x better than what Konami produced, the PES series would have died long ago, way before they ever had chance to cash in and make a kid friendly mobile game.
Konami owe everything to this fan base, who improved their product beyond recognition year up year upon year, a fanbase so dedicated and loyal that even after being fobbed off every year, lied to, fed mistruths, and had their pleas ignored, still stayed loyal to the series and invested time, money and dedication in to the millions of hours of PES related YouTube videos, live streams, forum posts, option file making etc.
Without all this Konami wouldn't even have a game left.
Yet, the betrayal, disrespect and complete lies that konami have pushed upon this fanbase shows absolutely no loyalty, respect or consideration, for the people who kept their product alive.
