I agree that games nowadays are overall easier than before, but then again, i don't like trying to get past the same section 11 times just so the game can be longer. I disagree with the part about new games lacking in the story department though. Mass Effect 2 has an epic story, while a classic like Doom has next to nothing in that sense. The only story Doom has is the text that pops up when you've completed a world. It certainly is fun to blast demons with a rocket launcher, but if you play games for the story, stay clear of Doom, which is an old game.
As for online players being bitchy, i haven't really played online enough to notice that. Probably because i'm a really sore loser myself. =P
Regardless, i know that the majority of the rather vocal online players happen to be cocknuts. Other players just keep quiet and focus on the game, and a third group is a bunch of nice and polite guys/gals who aren't shy of talking in a civil manner, maybe even congratulate you on a victory. I can't say anything about the distribution of people between these groups, but the first group tends to make itself the most noticed, unfortunately. I'm 99% sure that this isn't a new phenomenon, though.
