Even tho it is aging and it is beginning to show its weakness comparred to other more modern engines, it is still my most preferred engine and the only one I was able to get into succesfully. And with all of the updates Valve is giving it, I think the source engine will be with us for a long time.

I wouldn't really recommend this for a commerical product, just because there are so many more modern engines out there that will be a lot easier in the long run (like UDK), but all of the commercial games that I have seen on the source engine are fantastic (like Bloody Good Time ect.)

The Source engine is a must for just about any mod, it is very easy to change and manipulate the engine, there are a **** ton of tutorials floating around the internet, and also because if its good enough, steamworks!

Long Live the Source Engine.

Great engine, probably one of the only engines that my graphics card can handle.


Because i like games on Source engine like Half-Life 2, Team fortress and Counter-Strike: Source.

The best engine ever made for modding.

team fortress 2

I really love every game made with Source... it's all around a great engine.
I'd love to try to get in to development in Source!

Amazing! I have made so many maps using this! 10/10! So Easy to use too! It can be used to make so many different types of maps! I would definitely recommend it to other people who are looking for a easy way to make maps!

One of the best engines I have ever seen.

Why do I like it?

There are 2 main reasons:
Fully custom,
so you can enjoy anti-lag gameplay
for low end PCs or
Beautiful graphics for High end.

The Source engine has lots of potential,
(as titanfall has shown us)
I love this engine.
It gave me games
such as
Half Life 2, Portal
and Titanfall.

Thanks Valve.

Source may not be the most powerful engine, and its pretty old, but Source has held up and created such graphically intensive games such as Portal 2 and DotA 2!
