This didn't really have me very interested. It was still nice to see that crossover punchline. Well, we got two! The sprite work is quite nice. Tails doesn't seem to care that Sonic's head is on his plane. Well, he's probably blinded.
I don't know what Mario was complaining about. Why can't we have these characters in each other's worlds? All we have are the Olympic Games. The "Super Smash Bros" series don't count as one on one. Maybe Simon Belmont will be in the next one.
