Probably the GTA series. From 2002 when I first saw GTA III on a friend's PC back in 2002 and he installed it on mine, I spent the next five years playing and living in that game and its sequels. If I had a computer capable of running GTA IV I might have continued playing, but after finishing San Andreas I just had to quit; too much of my life and time was being taken up on those games. Other than that, completing SNES RPGs was an addiction for a while in the late 1990s, early 2000s. Harvest Moon, Chrono Trigger, Seiken Densetsu 3, Final Fantasy III... All great games and experiences.

MapleStory - played for 6+ hours at a time at work and had 11-year-olds ask why a 23-year-old was playing the game...

I used to love the Settlers games. Settlers 3 and 4 i've played tons of hours. But the new ones had a new format, didn't catch on to me, so i searched for another game and found Knights and Merchants, only to find that the only version available was a torrent copy in dutch. I can't read any of the text, but I found the right button for Random Map.

Also, I play Skyrim on super easy....

Just jailbreak it and throw PSX emulator on it mon frere

How can a topic like this not have anyone mention Everquest

hello ...

i'm a serial game buyer to then almost never play them ...

but to the few that got me hooked, MMORPGs are the ones that keep the wify yelling at me (CoX, since 1 year, Aion, DCUO since f2p on PC, purchased/pre-ordered & never unwrapped on PS3 & tried a lot f2p off steam, also bought but then stopped: Champions Online / Rift (may get back to that 1) ...

other games: Dungeon siege series (en cours...) / Diablo series (still have to finish LOD) ...

not far than the day before yesterday, the wify asked me if I had but 1 game ... & what are all those silly boxes on my shelf (*sarcasm*) ...

shame on me ...

cheers!
