Several years? I think you are exaggerating. I am pretty sure even making the game from scratch would not take that long. Well I can do some work in python. (Thanks to Oblivion modding there) Tethical does sound like it would be cool but if I were to work on a game made from scratch I would start my own so I could have complete creative control over the story and characters. Well I had not planned to program over those slots but to expand the number total and have the additional sprites load after the map and all. Now I am not sure how well that would work to have some sprites loading after everything else. Might cause them to be overlapped by objects loaded before but that is just a guess.
