For those of you undecided of your (next?) game-dev tool of choice, this website may help:

Personally, I'm not motivated enough to learn actual coding or an honest-to-goodness programming language, so easy-to-use SDKs like MMF2 (CT Fusion nowadays) have been my go-to for about 10 years now. I think I'm gonna pick up one of these FPS engines and see what kind of interesting stuff I can do with them... Lots of open-source and no-cost art tools in there as well.

Have fun, folks! :D
