Systems used to release many different versions of themselves. Such as Sega Genesis, with model 1 system, had a Altered Beast system, and a "Core" system without a game. Later there was a system that included Sonic 1 as a pack-in
Later, they did similar with the Model 2. There was a Core (No game), Sonic 2, Streets of Rage 2, probably some sports bundle, etc.
Sega CD model 1 I think had a Core System, and a Sewer Shark System. Later, the Sega CD model 2 had a Sewer Shark, Tomcat Alley, and some football game packages.
I don;t keep up with games as I used to, however all these pack-ins have seemed to have slowed down quite a bit. However, I have seen, 'bundles" advertised. In the past I've seen a gamecube in some blister packing, that included at least a game and a 2nd controller).
