6. Super Mario Bros 3 (NES)
We go from the finest 3D platformer ever created up to that point to the best and my favourite 2D platformer of all time (who knew they'd both be Mario games). It's been a long time since I last played the original, but I did re-buy it on the GBA, and that slightly more recent play through probably helped it climb a few places in this list.
Being a European, SMB2 came in the form of the re-skinned Doki Doki Panic, as it did in America, so SMB3 was the 'real' sequel to the original SMB, but it was well worth that extra waiting time.
Everyone knows what the 2D Mario games are about, but that doesn't stop this from being a true masterpiece.
