Chrono Trigger is my fav game for many reasons, but i used that recent in another giveaway
My fav First Person Shooter of all Time is between Team Fortress Classic and Day of Defeat/S
Played both of these games very competitively and always found a way to play better that I did the last match.
TFC was amazing, having played as just a Sniper for long time in the tournys and specialty maps back when the Laser dot lagged (u old hats know what im talkin about
Years of Concjumping and Skill maps which which created a monster in matched with a crobar
DoD however I played for a long time from original betas through to steam, and then 6+ years on DoD source, Beer Count baby, was the best place to play some Avalanche and knock out some kids
Between the two of them, i played for a very long time, had many success stories and have played with amazing people across the planet.
so, my favorite game.. is Valve
