Let's remember there are at least two sides to any deal - it's easy to be angry at EA but I'm just as pissed/disappointed with the leagues for entering into exclusive deals with EA that result in representing football in a watered-down, inauthentic, spirit-less version.
EA aren't going out of business anytime soon so the only ways forward I see are for Konami to increase the ease and options for community editing, or maybe some type of community-Konami combined effort to pressure individual leagues to end their exclusivity. The last option may be fantasy but consider: up until the last couple years PES dominated market share in some of the most important continental Euro markets, like Spain, Germany, France, and Italy. If they didn't have majority share they at least were close and despite the last few years, PES remains competitive in these locals.
It's unlikely PES will overtake FIFA in the UK or US anytime soon but if PES returns to form, as appears the case this year, then is it not inconceivable that PES will regain market share in the above mentioned markets? If the likes of Spain, Germany, France, and Italy are playing more PES than FIFA, would that not shift leverage to Konami, so maybe in the future they could attempt to loosen EA's hold on the licenses?
With the way big business runs the world (C.R.E.A.M.) and considering EA's massive clout I'm not particularly optimistic but a guy can hope can't he? When it comes to community edits and option files, EA has no legal way to challenge Konami's approach to allow us to include prohibited kits, names etc., right? I assume as long as Konami does not appear to be an enabler they are not breaking any law, no?
