Well, programming is stimulating. Sometimes fun, sometimes stressful, but definitely stimulating. It's good exercise for the mind.
It is Luca, exactly as you described. As soon as I find time to re-engage, I know I will enjoy it as well, as long as I don't exxagerate. I still have plans to port a 1984 game for the TI99/4A of one of my friends to the C64 once.
Great! Good luck.
