Used to play this in the computer lessons my school had. Great fun!.

It's fun at first but it gets boring as you play it.

Seriously nice music and nice gameplay. You can build your own cars and take it out for a drive (or be a mech). The satisfaction of driving the thing you spent half an hour to build is unexplainable.

Seriously fun and you can expect some some good laughs while playing this. Playing the campaign with friends (via mods) is also seriously fun. PS.: Some people may get offended while playing it

Nice graphics and fun gameplay. I recommend listening to some good music while playing this.

Even though using the weapons may be hard at first it's still a lot of fun

Poor mens Arma III and it's seriously fun

This is one of the best FPS games ever made. It still has a huge player base. I suggest looking at non-steam servers but be careful about the non-steam servers you enter.

This game is seriously similiar to the original CS gameplay wise but the graphics and the physics are a lot better.

Playing HL1 campaign with friends is seriously fun. And the best thing is you don't need HL1 to play this.
