You'd think there be more of a discussion here...
Well you know what? TNTBasic, which I am very excited about, has a built in tile map system, and would be ideal for a basic RPG. I think I can build an engine fairly quickly. (I know I'll have less time than some since I forgot about this. :/)
However, I already can build a map make collisions and add various objects so - Anyone want to join forces!?
I know enough programming to implement things I will need, I'm just less experienced with making an RPG work well. Most of the things learned from SC and GM should still apply, too, so if anyone has pointers for making, say, random encounters or a good inventory/item system... Heck, there was even a template on the site for "weighted" random numbers on the site, good for battles.
