A RPG include

Blitz3D Forums/Blitz3D Beginners Area/A RPG include

I'm planning on making a few rpg's in my life as a game coder. Ok, it maybe a stupid idea but, I was thinking of just making a .bb file that contained functions which most rpgs would use, and then including it into the main file of my rpgs. I would make this include available for free if I find some way to do so. What kinds of functions/types would people want to see if I did so?
This is a very future project, (I'm moving to no PC land for 6 - 12 months, ahh!) but I'm looking to plan the file out while I'm gone.
