Sonic & Knuckles works on it's own standalone as a completely different game, but it works as a plug-in to combine to make Sonic 3 & Knuckles...which is REALLY the full game, not Sonic 3. It is twice as big, with twice as much music.
Well, it came as part of the same product, so I don't see why I would break it up.
And, if it should matter, I'm going to count expansions as part of the base game. The only game I see this as likely to affect, should anyone nominate one, is an MMORPG like WoW, but I'm calling this out ahead of time.
