It sound interesting, but you also have to watch the legal reprocussions of doing so. Sonic is a trademarked comodity, and using it's likeness, or the name of a game which may very well still have a copyright held by Sega, can land you in hot water.
Ex. Just see

Also, if your looking for a programmer, you'll have to state what the language proficiency requirements and the amount of theory you expect an individual to know. You know: C, C++, MFC, OpenGl, Direct3d, Java, HTML, XML, ML, MIPS RISC Assembly, etc.
*Edit* Not that you would actually program a GAME in HTML, etc.
