Retro is no Rare. Retro is a great studio, and I'm not expecting it to have the same influence that Rare had.
But Rare had two things Retro does not:
1. They had full creative freedom. They didn't just create what Nintendo ordered them to. They created what they wanted
2. With this freedom, they created introduced new IP's and created the kinds of games Nintendo could never have created. They complemented what Nintendo did not have.
Metroid Prime 1, Prime 3 and Tropical Freeze are three smash hits. Classics. Amazing games. But I won't call Retro the new rare until they make a new IP and are given full creative freedom.
