I spent a long time trying to figure out how to make TI Basic programs fast enough to do games. Graph drawing commands were too slow! I realized that for most things text was the right way to go, but eventually I did manage to make a facsimile of Pong that was decently fast in graph mode by simply drawing each frame incrementally rather than clearing and redrawing it each time. Pretty obvious in retrospect, but I was still relatively new to programming when I first started messing with TI Basic. I also struggled to write shared routines with only goto, so my code was a catastrophic mess. I assume most TI Basic code was, though.
