My preferred system is HERO, currently on the 5th edition [revised].
Started playing D&D, then spent years w/ AD&D before moving to HERO, after comparing and contrasting it to GURPS.
I still buy books from multiple systems and just apply what I like to my HERO gaming.
Believe it or not I've actually never even tried a computer rpg (at least not a strictly turn based one). I can't help but find them too limiting.
I like making crazy characters with exotic weapons - shit like Hair Fu and Flying Guillotines
I don't have the benefit of a regular gaming group at the moment, but I derive lots of joy from designing battle maps and tactical scenarios, as well as making new characters each month [to playtest my scenarios with].
I also get a kick out of translating, interpreting events and/or items from various media sources into the rpg math.
