Shining Force - I love this game and even though 2 and 3 are bit more complete, the first one is a blast in my opinion. Plus it has more memorible boss battles. You can fight the battles over and over again and try out a number of strategies.
Castlevania SOTN - honestly i can just roam around this game and hack up enemies and try to collect all the "secret" items for hours. Plus once you're done...give it a shot with Richter. Good stuff.
Final Fantasy III - such an amazing game. I would play through using several different parties. Plus maybe I could finally conquer the collesium and learn all rage attacks!

Intellegent Cube - my favorite puzzle game. super addictive and fun. Challanging but not super frustrating. endless fun.
now....i need a shump. and it's a tough choice....but I'll have to go with
MUSHA - just a great game that is soo much fun to play. Awesome power-up's and bosses. i could/have played this game for hours and not once feel bored.

No rock band for me, but at least no one said guitar hero. On Rock Band you can actually change up instruments. eventually you may get so good you can do all them instruments at once. then if/when you are finally discovered you'll be some sort of prodigy.
