What I'd really like to see if some more arcade conversions of the late 1980s/early 1990s that were either completely stuffed-up ("Rolling Thunder" is one that still gives me nightmares!) or never happened (too many to list!).
The Amiga was capable of so much more, in terms or decent arcade conversions. But they were frequently crap, as the programmers/publishers were often after a fast buck - quality was never part of the equation...
Mike.
