I've noticed over the years that I don't get much enjoyment out of playing computer games.. but I still love reading video game reviews, and vicariously enjoying the magic ability of a video game to transport you into a imaginary world.-mouser
I have found as I have gotten older that I love playing games just as much as I used to, if not more, but my free time to do so has dwindled to such a small amount that I don't have nearly the time to play every title that catches my eye.
What may be the factor that explains our different opinions on games may be the different genres of games we play. I prefer games with strong RPG influences like Fallout 3, Oblivion, Diablo (I and II), and Sacred 2.
(Side note to f0dder: If RPGs fit anywhere into your bag of interests give Sacred 2 a try if you want to see the good/evil campaign choices done right.)
I've never been into the MMO thing, either. The under-18 crowd are a bunch of game enjoyment-killing ass-hats & the over-18 crowd is predominantly unemployed people living in their mother's basement who do weird things like to get 'online married' on a mountaintop in the middle of a raid in World of Warcraft & other socially deviant things like that.
