I think is a good game engine and the games with this engine are really nice. ///9 (Sorry about my bad English)

Very flexible engine from my expirence with all the wild mods that are avalbe for it, only thing is that it seems to be easy to exploit.

Despite it's age, the source Engine is an ever-expanding, fully functional game engine with many perks and capabilities that I feel make it an excellent choice for Game Developers and Modders. While it lacks some of the qualities that other Engines posses (such as DX10+ Support and Large-Scale worlds), Valve's continued efforts to expand upon the Engine to insure that it remains compatible and glitch-free are certainly one of the many reasons why for 6 years and counting, people from all across the globe are playing and modding the games blessed with the power of Source.

I hope Valve never lets go of this one. Great graphics, sound, effects, and online support.

May sound crazy but i like gold source better. This is still fantastic but it is missing one thing that will probably come to it one day. NOSTALGIA!


Very good, a little outdated but very good.

It's pretty good, but can be buggy as hell.

It can be buggy and a hassle, but if you work with it you can produce great results.
