Are you seriously going to make the argument that COD single player campaigns and NFS car selection (not track selection necessarily because the way that series has gone with open world, there are a very large number of distinct tracks) are okay the way they are? Because if you are, I'm going to call you crazy, they are lacking good sir. People's lust to buy something does not automatically mean the developers are doing right by their legacied fans in giving them new content. Hell, with NFS, you can make the argument that they've been taking content away.
SM3DW is a bad example because that game has like 4 endings and a secret world behind each one, you are getting a fantastic value with that game.
Using this example though, while 32 racetracks are just fine (why not 40 doe
), how many babies and metal characters are there padding the roster? It's a less serious example but...::Shrugs::
