I finally got around to playing Mega Man and Bass, the last of the sidescrollers in the series that I haven't played yet. It could use way less instant-death traps (I know, it's Mega Man, but they still overdo it even by those standards), but it had the best overall selection of boss fights in my opinion, as well as way more replayability than normal due to 2 characters, collectible data disks, and lots of choices with upgrades. Plus the graphics and animations are amazing, with normal Mega Man music (in other words, really good).
