You sound kind of like me. I've played about all I can of Guitar Hero/Rock Band. although in it's prime, it was awesome. And I agree, playing a console game is harder to record, so i'd stick to something you can play on the computer.
I think RPGs are awesome (of course I do, i'm on this forum). In that aspect, i'd most likely venture into snes rpgs. I finally took the opportunity to play chrono trigger a while back since everyone was hounding me to play it. Games like those you can't go wrong with I think. Plus, I believe snes is the mother of all great rpgs.
So yea, I'd definitely do mother 3, chrono trigger, bahamut lagoon, something like that. There's still a million good RPGs I haven't even touched yet ):
