Games where the lead platform version was canned, but another was released

Dark Angel: Vampire Apocalypse was originally developed with the Dreamcast as the lead platform. It got canceled, but the PS2 version did get released.

Any other games like this (any system)?

Grand Theft Auto was developed initially on Saturn, alongside the PC/DOS version but due to lack of resources and the Saturns waining popularity development was halted and solely carried on for DOS.

Shenmue started out as a Saturn game, too, IIRC (Hence the Saturn in the Hazuki home, despite being anachronistic).

Shining Wisdom was designed for the Mega Drive and changed for the Saturn last minute, they wanted to bulk up the Saturn library.

I'm talking more about games that were originally intended for more than one system. Dark Angel was going to be a DC & PS2 game, but only the PS2 version came out, despite the DC being the lead platform when it was in development. Shenmue was just moved.

Half-Life for Dreamcast?

[goatdan]

There are a ton of games like this. It happens when a game is started for one platform and then for whatever reason that platform goes out of style, or the company switches hands.

Offhand:

Grand Theft Auto 3 was supposed to be Dreamcast
Tomb Raider was originally going to be Atari Jaguar
Kameo: Elements of Power and Perfect Dark I think were both supposed to be GameCube (as was Grabbed by the Ghoulies if I'm remembering right)

There are dozens of other games like that. Using the criteria of it needing to change both platforms and manufacturers, look at anything around the end of the life of the Jaguar or Dreamcast, as both of them were lead platforms for a number of things that ended up going elsewhere.

Half-Life for Dreamcast?

Half-Life's lead development platform was the PC. And I don't think anyone knows if any of the Dreamcast code was used for the PS2 build (I'm not even sure the same developer was responsible for both porting jobs).
