Which is the oldest game you're still playing today :)

Counter Strike 1.6, and i still think that this game is best LOL

I sometimes play random NES/SNES games when I feel like it.

I still play Super Mario RPG once a year or so. That game has had a hold on me ever since it released.

I'm looking to play Runescape in the next months bet it ain't that easy to be good at it.

Counter-strike go for sure, still play it around 60 hours / 2 weeks

Deus Ex 1, Max Payne 1 & 2, Left 4 Dead 2. Fallout 1 & 2

mario on the original nintendo... no idea how my system has lasted this long

Garry's mod and team fortress 2, very good games in steam

Half-Life, Deus ex, Counter-Strike and tetris. I really like to keep old games on my spare hard drive in case the internet goes out and I need to play something

World of Warcraft and Warcraft III (old one not reforged) still amazing gameplay after all these years
