True story - when I played through SMG back in 2007, I played it in the fashion of a completionist; not advancing forward until I got all the stars in a level. Unbeknownst to me, the final boss and ending of the game becomes available once you obtain a certain amount of stars. So I beat Bowser and I reach the end credits, and while I have technically beaten the game, I've also missed an entire half of it. Did 2007 me feel compelled enough to play through all the other levels?

No. I sold my copy of the game and moved on.

So the reason I'm giving this 3/5 is that, even though it was a long time ago and I don't remember SMG all that well, I do remember that I didn't like it enough to check out that whole other half that went unplayed.

Super Mario clearly is not for me.
