For the first time ever, I recently completed a Pokemon game. My fiancee and I got Diamond and Pearl. She loves playing Pokemon because you can't die and it pretty much spells out what to do. When I finished I had clocked 50 hours in. That may be my all time record for a game.
I prefer a good mix of games. The top three in my library right now that get the most play are Wii Sports, Guitar Hero II, and Final Fantasy XII. I know I should like FFXII, and I'm really forcing myself to like it, but man, that game is SOOOOOO SLOOOOOOOOOOOOOOOOOW.
I'm a lot more of a casual gamer than I used to be. When Wind Waker came out, I played it for two or three hours a day for a month and a half straight. Now, I'll play for maybe an hour before doing something else.
It seems like I'm playing more of the "gimmick games" anymore. Katamari Damacy, Phoenix Wright, Puzzle Quest, Guitar Hero, Trauma Center.
I've got a season I've been playing on NBA Courtside 2002 since the game came out. (I don't trust the game to simulate - the one time I did that, my team lost.) I'm in the conference finals of the playoffs right now, though.
If I'm headed to a movie early, I'll take my GBA and play a few holes of Mario Golf. Unless I'm doing really well on a course, I can turn it off and not care because my golfers are all maxed out anyway.
I am a pretty interesting gamer. Some days I'll want to game for hours, most days I won't.
I used to be obsessed with gaming when I was a teen. I could play a RPG for 12 hours straight. I can't really do that any more. I have the time, just not the motivation.
Lately I've been trying to get back into gaming a lot, and sometimes it works. I did get hooked on Xenosaga Episode 1 and Suikoden, and I am playing through a few other RPGs as well. It's just that one bad thing happening (I lost an hour of progress in Seiken Densetsu 3 and haven't played since, got pretty far too.) can sometimes kill my motivation.
I love gaming though and always will. Right now I am on a goal to beat 52 new games this year. I'm currently at 14 and hopefully the practice I am putting into some NES games like Snow Brothers will pay off and that number will explode.
