The problem for genuinely dissatisfied purchasers of a game like FIFA 10 is that there are too many people complaining about non-issues like game play, difficulty settings or referee decisions, etc; FIFA games have always presented the player with challenges that are sometimes seemingly unfair, but one learns to play around them or stop playing that kind of game.
But all such discussions do is cloud very real issues over product quality, product liability and customer rights, none of which seem to be very high on EA's agenda these days. Indeed, given the volume of complaints about FIFA 10's virtually unplayable Manager Mode, one might have expected some kind of fix (if not a recall or offer of a discount on FIFA 11) to be forthcoming, but instead all we get is yet another pointless add-on (Ultimate Team) that seems not to work for most people who have actually succeeded in downloading it, and for which one will be expected to pay for the privilege of playing! In the meantime, FIFA 10 owners with real complaints are being ignored by EA and their vendors. It is a disgrace.
I for one am unable to play beyond the fourth season in the EPL because of a bug that has caused promoted teams to be duplicated in the league table (ie, there are now two Wolves and two Middlesboroughs!!). EA have not bothered to reply to two letters I sent to them regarding this and other bugs, and my vendor is also unwilling to take issue with EA on my behalf.
The following threads should give some insight into the most serious issues with the FIFA 10 Manager Mode:
EA Sports won't care about the quality of their products while there are still people willing to buy them season after season; I say stop buying EA products. If you want to play a sports game, buy an old version that is known to work well and update its squads manually... that has to be a more valuable way of spending time than battling through three campaigns only to find you can't go any further because of bad code.
