I personally got started hacking around with a Commodore VIC-20 but there is nothing as basic (excuse the pun) as this, which would create a nice gentle learning curve, around these days.
Really looking for suggestions from others that might have done this or know something about it.
I would assume it would have to be an interpreter-like environment, with easy ways to make pretty and interesting graphics/sound effects but some ability to increase complexity to simple game programming levels.
Open to all suggestions.
