GoldSrc

In my opinion, GoldSrc is the best for modding. It's very outdated, but if you don't mind lower graphics, but still want to make some cool maps and stuff. I used GoldSrc to turn TF2 maps in to TFC maps. However, I would like to expand my modding experience into other engines, do you have any recommendations.

Thanks for the responses guys! I really appreciate it.
I can't say anything on this, since I have never made a map or mod, only thing I've ever done "moddy" was changing the texture of the door in Minecraft to have glass, and that was with a version where every texture was in 1 file
