Final Fantasy VI...That is all.

Probably Pokemon Silver... I put at least 250 hours into that game...

Oblivion, followed by Pokemon Gold and then Timesplitters: Future Perfect. :p

Just Cause 2. I got really addicted to it for awhile.

Pokemon Pearl. 309 hours and 25 minutes, and counting.

I don't know the exact hour count for any others, but Super Smash Bros. Melee and Animal Crossing: Wild World are both games I've probably spent a week or more playing.

GTA San Andreas.  Not sure how long I played this game, but I think I got close to 180 hours all together.

GTA III by a pretty wide margin. Second I don't know, probably one of the old Pokemon games.

The Elder Scrolls: Oblivion, lost count at 420 plus hours.

Modern Warfare 2 lol. I had like 26 days in time played on multiplayer alone when I sold it.

I can't believe I'm saying it, but there's a real chance that Dynasty Warriors 6 is on that list.  I played that game for years, quite often, and STILL never beat it.  Not even halfway...*** you Lu Bu!!!!!

For me, I'd say The Hulk for the Gamecube.

Spent 3 Months, 9 hours/week, 5 weeks/month (135 hours)

Lost Planet 2. So many nom de guerres to go back for. I think I've spent maybe 120+ hours playing and I'm still no where close to getting them all.

GTA 4 all stories

It's probably between Pokemon Red, Blue, and Yellow versions when I was a kid and Fallout 3.

Oh, and Original Super Smash Bros. which I played after school almost every day for years.

I'm going to cheat and say a series. The Quest for Glory series for the PC easily consumed 500+ hours playing and replaying them over the years. Classic point and click gaming at its finest.
