Ummm, we're not talking about the X series, though I guess you could. It's easily the inferior series

Megaman 5, on the other hand, which I was just playing earlier (I JUST GOT THE COLLECTION TODAY FOR $25, YIPPEE), is a damn fine game. Poorly underrated (along with 6). Great original ideas for boss names, levels, etc... and collecting a letter every level (spelling MEGAMAN5 and getting something out of that), adds the Rush Jetpack and Power Suit, etc... great stuff
