15. Super Mario World (SNES)
Mario has always been a major part of my gaming life, but for quite some time, SMW was my gaming life. I played nothing else until I found every single exit, got the maximum amount of lives and maxed out the score. It got to a point where I could probably play certain levels with my eyes closed. I've lost all that ability now, but I still love this game. And the funny thing is, despite all that I did with this game, it isn't my favourite Mario game, in fact it's not even close to being my favourite, as you'll see as this list reaches its conclusion.
