When all is said and done, the thing that really makes Super Mario Galaxy such a standout game isn't the fact that it's another Mario game, but the fact that it doesn't even need to be a Mario game to be successful. Sure, it's got all the nostalgic flavor Mario fans would want, with the updated soundtrack, familiar foes, and various other Mario-related bric-a-brac scattered throughout the adventure, but the game never leans on these nostalgic aspects as a crutch. It instead puts the whole of its focus on its gameplay design, and with good reason. You could probably swap in just about any other characters from practically any other franchise, and this would still be a phenomenally fun game. That it layers all these memorable characters and components on top of that phenomenal design just makes it all the sweeter. If ever there were a must-own Wii game, Super Mario Galaxy is it.
