Hoya!
I do NOT really believe 3D could "improve" a 2D game.
Those are two different feelings and concepts.
What would be cool would be former Amiga programmers coding games for the new Amiga... But using their unvaluable know-how!
As for Turrican in 3D... Well, the major point of a platformer is being able to see from the side. 3D would totally kill it IMHO.
