Yeah, sort of like those "32 in 1" and "112 tele-games" Atari cartridges, where each "game" was a permutation on the number of players, how the players were organized into "teams" combined with difficulty levels, or some such modifier. In reality, it was just the same game, and maybe you passed the controller around differently.

Or the cheap "pop station" handhelds that blatantly give you multiple copies of the same game, just with different "sprites": snowboarding, skiing, motorcycle racing, car racing, bike racing, etc all effectively identical.
