7. Super Mario Galaxy
Super Mario Galaxy has everything a platformer needs to be great and more. Superior level design, excellent gameplay, simple yet effective controls, clever use of gravity (it's always fun trying to jump around a planet) and a soaring soundtrack all make for a truly spectacular experience. Playing through this game is simply a joy from start to finish, it is never a chore, and that's something that not many games can match, and the ones that do are probably other Mario games. There's so many standout moments that it's hard to pick out a particular level as the best, but there is something special about some of the early levels where you're flying through space for the first time with the soundtrack blaring and you see your next planetoid approaching. Despite all that, it still isn't my favourite Mario game, but we are now into the top 3.
