Old School Games Included With Their Newer Counterparts

[Classic Speedy]

Hey everyone, I'm looking to compile a list of newer games which have their predecessors or previous games included as either an extra or unlockable. I know of these to start with:
-Tekken 5: Includes Tekken 1-3
-TMNT 2 Battle Nexus: Includes TMNT: The Arcade Game
-TMNT 3 Mutant Nightmare: Includes TMNT: Turtles in Time
-Outrun2: Includes arcade Outrun
-Return to Castle Wolfenstein: Includes Wolfenstein 3D (PC version)
-Mortal Kombat Deception Kollector's Edition: Includes MK1 (arcade version)
-Metal Gear Solid 3 Subsistence: Includes Metal Gear 1 & 2
-Virtua Fighter 4 Evolution: Includes VF1 (enhanced arcade version)

Are there any others? (please note that compilations don't count, as they are purely made of old games)

Donkey Kong 64 had the original Donkey Kong and Jetpac

Mortal Kombat: Shaolin Monks had MK II, I think.

Prince of Persia: Sands of Time had one of the two originals as an unlockable, depending on which version you bought.

The newest Pitfall game had the first two Pitfall games as extras.

Shenmue - Hang On! and Space Harrier
Shenmue II - Hang On!, Space Harrier, Afterburner II, and Outrun

Oh, I almost forgot that Final Fight: Streetwise contains the original Final Fight.... sort of. It's such a poor port job that it practically doesn't count.

Any others?

I believe that the Genesis version also had the atari version as a bonus.

Can someone clarify this for me: Looking at some GameFAQs codes, it appears that in the Area 51 remake, there's an Area 51 arcade machine hidden in some level. I assume that's only part of the background and not actually playable, correct?

Rampage: Total Destruction includes the original arcade Rampage and Rampage World Tour as playable games in the retro games/bonus content menu option.
