I do set Waluigi to Very Hard, otherwise known as B ranking.
I set Dry Bones and Blooper to Weak (Easy), otherwise known as E ranking.
But I usually set the characters to Hard and Very Hard.
Mostly when I play this with friends, the difficulty levels for Computer Players really varies and/or depends. Mostly Normal though, but sometimes we might set them on Hard.
Usually normal becuase the SPU's aren't so annoying on that level, which means most of the time.
The only reason I'll choose hard so for a great challenge, which I always enjoy when I'm in a good mood, so occasionally.
Depends on the game for me to put easy or not, and that means rarely.
On All of the games i have it on Normal difficulty until i am fully Connected with the minigame i play. When i start to play it, -Normal difficulty- When i get used to it. -Hard difficulty- And when i Am feeling confident and lucky -Very hard difficulty- Or if were talking about mario party 6 -Brutal difficulty- ^-^
Sorry i just like to talk alot.
