I downloaded this on PSN the other day for $9.99. Haven't had too much of a chance to play due to work, but I have to say that the 45 minutes I did put in were frustrating- but in a good way. There are so few games anymore that actually challenge you... everything has a cheat or a hint or a workaround... MM9 (similar to the original Mario Brothers) forces you to "execute", for lack of a better word, and you have to pretty much be perfect. I look forward to dedicating some quality time this weekend.
