It was the first mk I ever played so I loved it initially. Now I rarely play it because I own mkwii and mk8d and it just feels boring in comparison to those games.
When I beat that game I didn't do a complete playthrough and just got to the end. I thought my time would be better spent beating NSMB2 instead of a 100% playthrough.
Just about everything I've played so far in spm has given me chills. But I guess that is what makes me love playing the game. Also the final battle in mario galaxy got me so scared I could barely think cause I couldn't afford to lose a life.
