What was your first game you loved?

The first .hack series had me seriously enraptured. I love IMOQ (Infection, Mutation, Outbreak, Quarantine) so much. I see that most people appear to prefer the 2nd series of the games (GU) but I still prefer the first one. Maybe I'm an odd one out. A lot of folks complain about the combat in the first series but I'm fine with it. Though when a friend played they commented that my play style was way different from theirs, so maybe that's why.
