Not to hijack

, but i recall my first multiplayer game - 1200 baud modem playing on a BBS tradewars. I played on my dad's computer at work - boy was i hooked on opponents even though that's not a first person shooter.
Half Life - missed the first one and got hooked when the 2nd one came out - don't remember how long ago! I really only play on this server as I'm annoyed by the no rules and foul language of other servers. That said, this is the only game i still play. I'd guess my late 30's then LONG past OP 6!

...
Only game I'll likely try in the future is Borderllands 2 - love the first one in regards to solo play - very entertaining!
