Ever try to do multiplayer on a DS game? We're really sorry to hear that. It's a mess of lengthy friend codes that does more to discourage online play than enable it. That's going away with the 3DS. At Nintendo's 3DS press event in New York the company announced a new system where there's only a single code, assigned per-console and registered only once. You'll have a single group of friends and, when they pop online in a new game, you'll see them there. No need for multiple lists and, we hope, less of a need for Tylenol.
