I played quake every day until Quake 2 came out ... then Quake 2 every day until Half life came out, then Half life every day for probably 2 or 3 years ....
I play Total Annihilation at least once or twice per week still ..(and it came out when, in 96 or 97?) Greatest RTS Game EVER IMO ...... (been playin with the AA mod, haven't had a chance to try "Spring" yet, though it looks VERY promising ...)
