Call this game "Quake III" it's unless, because it's not a III, but it's like an apart chapter. Funny, fast, addictive and still an active multiplayer.

All loves Team Fortress 2, but how many fans of Team Fortress 2 came from the original? I think nobody. Still a very active community and very fun.

Open-world, black humor and just crazyness into one game. What do you want more?

One of the all time bests. You would be crazy not to play this game. Great storyline, great gameplay, great everything.

Half-Life is not a game, but an experience, and maybe one of the best videogames's experience you could ever do in your life. You HAVE to play it.

The second and maybe the second best chapter of the amazing Quake's saga after the first one. If you played the first chapter, you can't miss this one.

The original Aliens vs. Predator. A nice fix of the Gold Edition released on '99. Still an active community with tournaments and matches too.

The FPS which started all others FPS after it. Competitive and funny, and when you learn this game's basics, all others will be a joke.
