I think this is the most likely of possibilities, developer or sub contractor given a spec, to his mind delivers it, Sega say it's not good enough / not what we wanted and dispute ensues, and eventually a payout / agreement. It would explain the complete lack of any information from anywhere about it - not just from Sega, but from the developer or sub contractor who developed it. We don't know how far down the line R2 was before it was scrapped, but it is surprising that there are no assets that have been found after all these years, and it's my feeling that the level was quite far into development - quite a bit of time and money already spent before it was scrapped. R2 is something I'd like to see resolved. Think it was mentioned earlier, sound test 10 in Sonic 2, what is that little piece of music for? I'd also like to find out a bit about the 2 player stages in Sonic 3 - conceptually there are some really interesting ideas there that would have been nice to see fleshed out into full zones - Azure Lake I always thought was beautiful. Where they scrapped 1 player zone ideas? Balloon park clearly gets its inspiration from Carnival Night, and Desert Place from Sandopolis. Endless mine?
