I know it's slim, but considering it would mean better looking Wii games (perhaps even letting some HD game be ported, considering the scale the engine allows) and more money, it would just be a damn good idea.

Only if the engine is flexible and easy enough to use to make different games. It takes a lot of work to make an engine with these attributes, and I'm guessing it's not something most developers do especially when pressured to finish a project.

EDIT: Why not the Metroid Prime 3 engine instead though?

Could work, but also need the criteria you stated.

the twilight engine was probably made specifically for what a zelda game would need graphically, so it would probably not be possible to be used easily in other games.

it's why twilight princess was a great looking gc game, and why super mario galaxy is currently the best looking wii game.

From my (very limited) understanding, most large Japaneese developers' "Game Engines" are not designed to be stand-alone products in the same way that Epic's Unreal Engines (or Valve's Source engine) are ... Essentially, they tend to be a collection of large (poorly documented) libraries that (tend to) require a certain familiarity to accomplish anything.

I could be wrong but I suspect that most developers would (probably) be better off taking Panda3d (http://panda3d.org/) or one of the Open Scene Graph projects (http://www.openscenegraph.org/projects/osg http://opensg.vrsource.org/trac) pairing it with ODE (http://www.ode.org/) and making the necessary modifications/enhancements to create their game.

Okay, so it's probably not in an engine form. Damn.

Well let's see what Quantum 3 can do.

In my opinion, it'd be better for all involved (Nintendo, the Wii, the developers, and us) if they licensed out the Metroid Prime 3 and Mario Galaxy engines.

Those two were designed specifically with the Wii in mind, they both can render massive areas with nary a framerate dip, and they're GORGEOUS!

Also, I think High Voltage said they'd consider licensing out the Quantum 3 engine once The Conduit shipped, if anyone was interested.

Most of us know that already.
