I wonder what proportion of the average user’s rom library is from the 87%

Lots of great options already, but I’ll throw in WarioWare on GBA since I haven’t seen it mentioned yet. Lots of super-simple fast-paced minigames that are nice for a quick playthrough if you’re on the go.

Some of the GBA remakes also added in voice tracks, like Mario saying “Just what I needed!” whenever you get a mushroom, or Link doing his grunts and “hii-yahs” whenever you swing the sword. I guess I could see how some people might think those were neat, but I mostly found them annoying, especially given the quality of the GBA audio.
