I didn't think any of the characters in Melee were necessarily "hard" to unlock. I thought they were more "tedious" than anything.Calling it now, Mr. Game & Watch is unlocked by completing All-Star Mode on Intensity 5.0 or Higher.
Because it's a nice callback of HOW HARD HE WAS UNLOCKED IN MELEE! >:|
Like Mewtwo, you had to do 20 hours of VS, or 500 VS Matches.
I personally took the cheap way out, and plugged 4 controllers in, started an endless Melee, and left the system on for 5 hours.
And Mr. Game & Watch was unlocked by completing Classic Mode, Adventure Mode, or Target Test with all the other characters, on any difficulty, or playing 1,000 VS Matches.
I just carelessly ran through Classic mode with everyone on Very Easy.
