The old Command & Conquer series (Tiberian Sun/Red Alert 2, 1999/2000) still have an active mod community. A significant factor is a few dedicated people who reverse-engineer the engine and make C++ patches/additions to it, giving regular modders much more power. I used to be one of those people reverse-engineering Red Alert 2, and those years were certainly fun and challenging, as well as illuminating in the "this is why you don't <bad coding practice>" sense. Fun fact: When EA repackaged those old C&C games for The First Decade bundle, they removed the No-CD checks. Most of the games were recompiled to achieve that, but since Red Alert 2 had these engine patches relying on absolute addresses, they went through the trouble of hex-editing the executable to keep the patches working.
