It is actually - I've done quite a bit over the past two or three years and 6502 assembly is really nice to program - it's hard to explain, but the fact it only has three registers combined with a relative ton of storage space for variables means you're constantly doing this three-card Monte shuffle that is very satisfying.

It's also all eight bit, obviously, so you're also dealing with nice, human manageable numbers of 0 to 255.
