Wow, thanks Joe! The thing is, I haven't actually played any of these games except for Daze Before Christmas (and that was on an emulator). All of these games are good, surprisingly (I did mention that the GBA and DS ports of Elf Bowling are crap, though).
I simply researched these, and I also have experience with NiGHTS, but it's the Wii game, not the orignal. The NiGHS games are pretty simple and easy, but very fun. You fly through the levels and collect points by flying through rings. The bosses are the best part; they're very creative, and you have to figure out what to do in order to beat them (it's never the same thing twice). Thanks for reading!
