Holy shit yea. That was the first online game I ever got into, and was still playing it long after quake 2, half life and team fortress classic got released. Best game ever. I eventually got into quake 3 fortress, wich was a good remake. Check out fortress-forever.com for the next remake..
Did you hear, Vavle is releasing Team Fortress 2 with their upcoming half-life 2 episode 2? Check out the trailer... looks kinda wierd. They took it a very cartoony route.
