No. 7 Super Mario World (SNES, VC)
Simply put: 2D platforming perfection! This is one of the few times I'll say "if you disagree, you're wrong!". Nintendo took the gameplay elements that made the NES games great and perfected them. Then they gave you a dinosaur to ride that could eat up your enemies! (Yoshi FTW btw). This is quite simply the pinnacle of 2D platformers. Nothing even comes close in terms of quality.
Other than the gameplay being perfect, it also had hundreds of diverse levels, some beautiful worlds to explore, brilliant level design and countless extras and hidden worlds with ridiculously hard challenges. I found the artwork especially enchanting as it really worked my imagination; I genuinely felt like I was in this amazing world where dinosaurs and plumbers could co-exist :P
I'm sure nostalgia plays a big part of my love for this game, but it's one of the few games I keep going back to just for the sake of playing. Give me a SNES and Super Mario World and I'll be satisfied for many years.
