I’ve been hesitant of the mega man games for some reason, I’ll check em out!
I can understand that hesitancy for the NES games. If you never played anything like them, they can feel unfair or too hard. A lot of people love Mega Man 2, but my personal favorite of the NES era is 6, which could be a decent entry point if you ever decide to venture that way. X improves everything and the first is my personal favorite as well (it easily has the best music of the 3, too).
