First thoughts.

I've played Megaman Legacy Collection for a little bit, and I like it. It's got a save feature that allows you to save your game anytime and allow you to continue right where you left off. And when I say right where you left off, I MEAN, right where you left off. That way you can keep on trying the hard parts of levels as much as you need to without losing too many lives. Also the databases allow to look up the Hp, attack, and weakness of enemies so that you can plan ahead. I haven't done too many of the challenges yet, but the one I have done was fun. In any case, If you ever wanted the first 6 Megaman games on a portable gaming system, this is for you.
