The more rare, obscure, or just a guilty pleasure, the better. Maybe you grew up with it, maybe it’s just the nostalgia talking, any reason is fine.

My favorite is games for original DMG, but you’re welcome to include Color it’ll advance games too!
Just FYI, there's a 3DS remake that has an English fan translation patch.
