Grimrock

I have a question for the people who have made or are making LoG1/LoG2 mods:
Do you use a version control system, and if so, which one?

I am strongly considering using Git for the ORRR3. I would probably only check in the scripts (and I would do that between sending it out to people - so nobody else has to worry about it), but I feel it would be nice to roll back if anything breaks.

I would generally recommend using version control for as many things as possible, but I don't use it for my Grimrock mods because they're mostly binary files (models, animations, textures, audio) and using full version control for those would fill up my small hard disk really, really fast. Instead I keep intermediate format versions of files (.blend, .xcf, .aup, etc) where I need undo history or the like. As another time-saving measure I keep all textures uncompressed until release, but of course that requires that you have enough video memory.
I do keep external backups.
