Little projects...

Okay, I'm doing some little projects with games.  The projects are basically remixes and medleys.  One involves games that have a time traveling theme and the other involves games from SEGA.  The SEGA part is easy for me, but I'm having a bit of trouble with the time traveling themes.  So, along with Chrono Trigger, Ecco the Dolphin, and Legend of Zelda OoT, what other games have a time traveling theme?  Please no suggestions on Back to the Future and Time Lord because I can't fit the music from those games into what I am puting together.

I'm looking at the game as of right now, it's called time pilot and it features simple levels of endless space where you fly around shooting at enemies that are themed for their time period, now, it isn't so much as a free form of time travel, or rather a freer form like every other game mentioned and that probably will be mentioned, but the important part is that I think it might not have any music, but if it does I have for sure never heard it.
