Dungeon Master on the Amiga 500 was probably the first, followed by the SSI silver-box Krynn series. Moving over to IBM-compatibles, Sim City ate a ton of my time. SC2k, various AD&D games, and eventually FPS games (especially Team-Fortress-Likes) came to eat up wayyyy too much of my time. My first MMO was FFXI and it ate about every waking moment I was not otherwise occupied. At work, I was looking up gear locations, mobs spawns, etc. and talking on forums. I would later go on to work in the MMO space and played a lot of them for work. Rift: Planes of Telara from alpha until the (first?) major revamp was the last game to really do that to me. Ever since, I will get briefly addicated to games, but nothing lasts… and that’s probably good with everything else I have going on. I do get super into Skyrim once ever couple years, though, and put an unhealthy amount of time into it.
