Nintendo has amazing potential for 3 things on the Wii.
1. Adult Games.
2. Lawsuits and Damage fees
3. Making you look like a total asshole while you try and execute motion-controlled cheats on the main screen of any given game, messing up 9 out of 10 times.
...not to say I dont like the Wii, i just dont have one.
And wait, do you mean codes as in like...cheat codes? there are websites for that stuff ya know.
edit: No, you meant friend code, like on the DS, right?
Im so confused.
