Mega Man 4 is underrated. Characters are big, weapons are fun, weird, and useful, music is great, etc. I am as confident in my love for Mega Man 4 as Mega Man is about completing his latest adventure.
The only issue I personally have with the game is that playing without saves takes too long what with those long fortresses.
It’s got some pretty noticeable flaws but, what game that gets name-checked on the Insert Credit forum doesn’t?
