I've been playing lots of different ones lately.
Dragon quest IX on the DS,
Golden Sun on the GBA,
Legend of Zelda: Ocarina of Time (Master Quest) - This one is really bugging me because I've got just two more heart pieces to find and I've completed the whole thing, 100% ! I just can't find them.
and The Legend of Zelda.

I'm in a similar situation as Beema, I've got quite a few games that I've owned for a while and I haven't played them much - So I'm planning on getting through some of them at the moment.
