I read through this as a 15 year old (I know, I know, I'm way older than you thought I was) just to compare what I had to say about it with you guys.
I don't care about anything but on the couch multiplayer. If I want to play with people online, I'll play an MMO.
I'm okay with the lengths of games, but I've never played more than a few hours of those several hundred hour games.
Games' storylines are compelling for me now then ever. Except Kingdom Hearts 2's storyline. That was the opposite of compelling once it lost its magic.
I've always said it and I still hold to it, "I don't care if its the biggest ripoff ever; just so long as its a good ripoff, I'll enjoy it."
Games used to be about fun? I'd never have guessed.
As to how much time I get to game... it depends on how much homework I have that week. Some weeks I may have upwards of 10-20 hours to play games, some I may have a total of an hour. Gaming still hasn't lost its appeal to me, the appeal just changed from when I was little (ooh, fun) to what I am now (ooh, storyline).
