Pokemon B2/W2 have it. But it might just be local wireless, I've never tried.
No, it includes online wifi as well. I'm hoping that X and Y will have it too. --- Brawl FC - 1332 8069 6690 "Gravity Rush is 1458 Mb the 58 Mb should more then cover the missions/dialog/character models" - Demondog666
due to nintendo's wfc rules public in-game chat is not allowed (to my knowledge) but if you are connected with a friend it is... games like pokemon and call of duty on the ds had these features...
(somewhat) unrelated: there is a voip homebrew app for ds which can allow you to call people's phone --- 3DS Friend Code: 2294-3549-5852 Accounts: Twitter ilikepie641 / Deviantart ilikepie641 / Youtube ilikepieism / Skype iateilikepie641 / Facebook Novotic Cosmos
Heroes of Ruin has online voice chat I think. I've never been able to test the online though. --- Former WWE Diva & BJJ Pink/Blue Belt. Smart. Sexy. Powerful. Eve Torres <3 http://bit.ly/J38z1u | http://bit.ly/KIjaFT
