Retro game as a bonus on a new game...

[the7k]

House of the Dead 3 for the Xbox had House of the Dead 2 as an unlockable. (From what I hear, never actually played it myself.) Dunno if that really counts as retro, but it's still an older game within a game.

Edit: Didn't Mortal Kombat III have unlockable retro games on it? Like, there was that 6-image code at the fight screen... been ages since I've played it though.

Edit2: Oh yeah, Pitfall was unlockable on Super Pitfall for the SNES.

Die Hard Arcade has Deep Scan in it. That's like retro inside retro. They must have heard we liked retro (dawg).

I can remember playing Pong on MK3. I think there were more hidden in there, but cant remember off the top of my head.

According to Gamefaqs, Galaga is also playable in MK3.

Metroid Zero Mission had the original Metroid in it.

So does Metroid Prime and Metroid Fusion. That's a lot of Metroid.

Shenmue II had Yu Suzuki arcade games playable in arcade room like Hang-On, Space Harrier..

[Segatari2002]

Panzer Dragoon Orta had the PC version of the original Panzer Dragoon as an unlockable game. Also, even though this doesn't really count as a game, Panzer Dragoon Orta also had almost all of the cinematic scenes from the previous Panzer Dragoon game series as a set of unlockable achievements. The best part is you didn't have to do anything to unlock them. Except play the game for at least 20 hours! Ha! Let that be a lesson to you. Nothing good in life is ever truly free!

Tekken 5 had the original arcade versions of all the previous Tekken games along with Starblade in it.

EDIT: Minus Tekken 4 and Tag Tournament of course.

Disc version only, or do you know if it also includes the downloadable Tekken 5 on PSN?

Donkey Kong 64 had the original Donkey Kong and Jetpack arcade games in it, but it's been far too long for me to remember if they were full versions.
