Just because something can be achieved doesn't mean that it ever will. Making a high class game for the Amiga (or any other computer) requires a significant team effort (not many people can do both coding, gfx, music, gameplay etc.) and since there is no economical reason to make an Amiga game today, it has to be driven 100% from passion. Not many people possess both that level of passion combined with the required skills to actually make it happen.
There are many people who start out on a project with great ambitions but eventually gives up on it before it is done simply because the most fun part usually takes place in the beginning of the project. The only real way to keep momentum up is to pay people (livable money, not pocket money) to do it. Without money I think we need some autistic people who are passionate about Amiga to make it happen.
