My original MM Ranking:
I think 3 is overrated. A long time ago I thought it was as good or better than 2 but while the core concept is great (more levels, more moves, Rush features), the actual level and boss design isn't as good and subjects you to way more BS/unfairness. 1 and 3 were both really bad for that.
I also didn't much care for 7 or 8. the art style, speed, gameplay, and feel of those games just felt off. Not bad games - none of them are - but wow I just didn't feel right playing them.
the first 6 were all immensely solid. 9 was outstanding, 10 was pretty good, too. 11 was also outstanding and the only non-8-bit game in the series I loved. I'm actually kinda surprised that, as of the time of this writing, not a single person has voted for 9, but there is a vote for 10.
