Personally, I'd really rather them leave their Dreamcast games on the fucking Dreamcast. :/ To me, that is by far the biggest mistake they have made since going third party. A few were certainly justified and made sense, such as the Sonic Adventure's to the GC, but by and large all the constant porting has done is tarnished not only the Dreamcast's image, but Sega's as well. They should have just had all of their studios go all out and pump out amazing new shit on the current systems, in the same vain as they did with the Dreamcast, only with their games finally being on systems that people aren't afraid to own, they might've actually been successful. But then again, Sega doesn't exactly seem to want to be successful.
