Again, the problem is the value on anything Genesis is low right now. There are some exceptions, but even a game like Knuckles Chaotix - which is rare - is trading low right now.
If you wanted to do it all as a set, I would list Knuckles seperately. List everything else together and you can expect about $60 to $70 for everything.
Oh, and sports game are generally never worth anything. They make them every year, so there's no reason to collect the older version when you can get the same game in the new version.
