I agree there's nothing wrong with venting but when it becomes a hobby and you don't even purchase the game any longer or really have interest in it then it's gone from being harmless to being self-destructive, as well as simply serving to clutter up the community in a non-productive way.
Case in point, when Lbzrule used to come on here and show videos of what was wrong with the football games. That's productive and demonstrative of how to improve the game. We need and I think should desire those types of complaints in the community. Even asking for specific things like socks, equipment or whatnot may seem trivial but that is also very specific on how to improve the product.
On the flip side all of the folks who come here year in and year out just to trash every screen shot, overanalyze everything said in videos, just in-general trash the game, trash EA and bemoan the entire state of videogame football really just serve to dispirit and disenfranchise those who still have an interest in and enjoy actually playing the game.
On a side note I actually think it's quite rude and arrogant for folks here to criticize those who do enjoy and purchase the game. I've seen it many times here when someone says they enjoy the game and/or plan to buy it that someone will scream at them "You're part of the problem" or just in general imply you're some kind of sucker if you buy the game. As I said, if people think the game is worth $60 then that's their choice. If you really believe you can tell other people how they should spend their money then you're the one in the wrong, not the person who is making a personal choice about how to spend their hard earned cash.
If you are one of those people screaming at others to not buy the game or insulting others because they have said they plan to buy it then you really are a deluded narcissist IMO.
