i agree about it hard to grow out of games.i just think that sometimes priorities make it a less appealing/or too time consuming option.
for a good while i didn't have any next gen game system (probably 3-4 years). the last system i had owned was a nintendo gamecube. the only games i would play were madden on ps2 against my friends.
then i bought a xbox 360 last year (and sold it a few months after due to $$ problems) .
didn't have anything till i got the ps3 again. Now that i have the ps3, i can easily get sucked in if i'm feeling lazy or stressed because these games are so engaging. So basically my love/addiction of games never changed, just my priorities in life shifted.
the thing that impresses me most about video games is unlike other entertainment (Music,tv, movies) the overall quality has gone up considerably recently. Sometimes when things change they often shy away from the core components that made things good to begin with. There seems to be alot more crappy movies overall(but certainly alot of good ones) and music, i'm not even going to get into. But gaming has completely envolved to the point where all your favorite things are still there but just with so much more to offer graphically, story wise etc.
