I can't remember the time when I would have been more anxious in waiting for a Live Arcade game than how I was while waiting for Mega Man 9. It represents everything that was great in 8-bit gaming and in my opinion Mega Man 2 for the NES is the best game ever made. Well... that and Metroid Prime I mean.
I've now played Mega Man 9 for about 2 hours and NOW I'm finally starting to get a hang of things. This game is difficult, but that's how games were back in the 8-bit era.
Everything is classic: music, graphics, level design, story and gameplay. It's great. I will produce a review in time.
