Mega Man 10 (Wii)
Got up to the first fortress stage with Mega Man. The bosses there are pretty brutal if you don't know the weaknesses, and I've only managed to figure out about half of them so far, so I haven't managed to get past there yet. I also played through a few of the challenge 1 challenges (which are like minigames, I guess), but got bored with those pretty quickly. Maybe it'll grow on me after a bit, but I have to say so far I don't think this is anywhere near as good as MM9.

Okay, I still couldn't work out a few weaknesses, so I just used energy tanks to get past the first fortress stage. The other stages weren't too bad, I had to use another tank to beat the new devil boss in the third stage. The final Wily fight was a bit disappointing, only because it had a huge leadup, but ended up being pretty easy. I unlocked hard mode, but want to play through normal as Proto Man first. He plays the same as he did in MM9, except his shield is bigger (easier to block projectiles with now) and he has access to the shop.

Got up to the fortress with Proto Man. Amusingly, he gets a smaller selection in the shop and has to pay more for everything.

Just watched some Bass mode footage from Vixy's live stream over at RPM. Hacked in, it won't be out officially until next month. It actually looks pretty fun, I was never huge fan of his gameplay in MM&B, but it transitioned over fairly well. Even gets the Treble Boost instead of the coil and jet. Takes normal damage, too.
