The Wii

Look up Brawl Plus and fix that up for him. Don't have him growing up playing an inferior version

Do not do this. Essentially changing the game he is playing to a different game from what his friends will have is a pit I wouldn't want to dig myself into personally.

First... I GOTTA KNOW HOW TO ADD PEOPLE!!!! =(((

Depends on what game you're playing on how you add people . You can add them to your wii message board as a friend, but it doesn't do too much other than let you send messages to each other.
