I remember getting upset at my cousin when I was little and was playing Kung Fu for the NES and he called the levels "stages". No, a stage is what opera singers perform, a level is a video game level.
Maybe that was a regional thing, though. He's from Kentucky and I'm from Maine, and there are any number of dialectical differences between those two places.
