If you're looking for a 3D development platform, give http://unity3d.com/ a look. Been developing a 3D web/smart phone game for the last year. I've also seen people do some creative 2D games on that platform as well.

Unity is great and possibly the only 3D solution right now, but there are better options for 2D out there for lower cost.

They have native 2d support coming soon, and publish-to-Flash. It was all announced in Feb so it hopefully doesn't take much longer.

What 2d tools are you referring to?
