That’s what a pack-in title is. I had one of those GameCubes, and I ended up trading in the packed-in Metroid Prime to EB Games for like $5 in store credit cuz I didn’t like the game.

I would say pack-in title would refer to a bundle that was active for a substantial time, like Wii Sports on the Wii. The Metroid Prime bundle was just active during the release of the game, 3 years after it launched.
