My opinion (Which, might I add, I have posted here with the purpose of it being disputed and/or discussed. Feel free, that's what the forum is here for); Mega CD.
- A Redbook audio soundtrack will allow for our musicians to experiment very freely for the most dynamic possible score.
- Through emulation, this can reach a very wide audience. Off the top of my head, Mac, PC, PSP and Mega CD users could all play it. That's a lot of people there already. Not as much as Megadrive emulation, but I'm combining this with other factors, such as;
- Playing on the original hardware is a piece of easy pie with the Mega CD format. Burn the ISO and go. This is appealing for many retro gamers (Who, by nature, will comprise a large part of the audience)
- The format is limiting in so many ways. This will ensure authenticity, but the added capabilities of the Mega CD will allow for stunning set-pieces or special stages.
- Coding for Mega CD is largely undiscovered territory here. I'm vaguely aware of a homebrew scene somewhere, but we can't be guaranteed any help in this area, nor should we take it for granted.
- Not everybody has a Mega CD. Not every Megadrive emulator emulates it, either.
- Offering an ISO that a person is essentially able to publish and possibly distribute themselves is quite likely to get us a cease-and-desist.
