Sure we all played games like Duke Nukem 3d, Warcraft 1/2 and starcraft where you can connect over the modem and enjoy gaming at a new level, but what was everyones FIRST online game playing with multiple people MMO style?
My first game that got me into the online scene was netWAR in 1997 (then uo shortly after, of course).. Dunno if anyone else played it but it was awesome back in the day.. It had online ranking system for k/d to see who was the best, and vehicles like helicopters/tanks. It was definitely tons of fun back in '97.. check out the link below for screens and review (funny seeing non 3d graphics)
