SWG - 1st
WoW - 2nd
Diablo 1&2 - 3rd
BF1942 DC - 4th

 

[Rakewell]

Borderlands
Diablo 2

 

[Worthington]

bf1942.. 1000s of hours over years.

 

[rh71]

WoW, easily... I can't believe my subscription history goes that far back... it's the first and only game I've ever subscribed for. I didn't like the idea back then but it's totally worth the entertainment I get from it.

 

[SMOGZINN]

Easily AustinMud, I spent more then 10 years playing that game often as much as 8 hours a day.

 

[thegimp03]

I've played Quake 3 CTF from the demo release in 1999 until now. Second most would have to be either BF2 or UT2k4.

 

[zinfamous]

Guild Wars.

ughhhh

 

[Sureshot324]

Counterstrike, original and source. Played each for like 2-3 years. Quake 2 is pretty high up there too.

As for single player, Oblivion and Civilization 2.

 

[BD231]

Madden franchise mode, everything else can only keep my attention for about an hour at a time.
