This is just a short medley of video-game tunes that I've picked up by ear over the years. I've been playing some of these since I began playing the piano, and others I've only just picked up (I'll let you guess which ones are which :P). I tried to give my own twist on these, as most other pianists on youtube tend to play them exactly as you would hear it in the game or on some unofficial sheet music. (yawn).
#1-Dire, Dire Docks (Super Mario 64): This one's almost become an unofficial standard on youtube, and for good reason. It's extremely simple, quite beautiful, and anyone who grew up with an N64 knows this tune.
#2-Grunty's Lair (Banjo Kazooie): I only figured this tune out recently while learning another song (Reflection Rag by Scott Joplin). As such, it's not really polished yet, and I decided to shift into Country Gardens for no particular reason :P
#3-Level Map (Super Mario World): Had a bit of a brain fart with this one, somehow.
#4-Outside (Luigi's Mansion): It's a nice, simple tune, and using the sustain pedal for nearly the whole piece gives it an eerie and ambient quality, especially on an upright.
#5-Sector X (Star Fox 64): For some reason, this tune is sadly neglected. Because nothing's ever happily neglected :P
