Not to put a dampener on things, but I don't see much point of a Windows version, that platform has GTA, GTA2 and now the new GTA 3. The whole point of Payback was to give the Amiga a taste of that genre, which was achieved as I bought it :-)
And as somebody said I thought the whole point of DE things was that you can run it wherever, from PDA to server if you wanted?
