Well, any new software is a bonus. Although I have to say that, if somebody wanted Sonic, they would already have bought it on another platform, so why should they bother with an Amiga version ten years later... even if it was a free download?
Most game ideas have been thought of, and once it's been made there are always a hundred clones or derivatives follow it. Any new game really needs to stand out from the crowd by virtue of being different.
Oh and Wolf... maybe you don't want Quake XXXX, Doom 3 or Half Life 2, but there are millions of people out there who can't wait for it. You seem to forget that the games industry is led squarely by the consumers. If we all wanted 2D racing games and platformers, why aren't they being made? People don't spend good money on games they don't want.
Anyway, good luck to you all on the project, whatever it may be!
