Why would that be taunting? If they don't add new communities when games are released, they're gonna accumulate one hell of a backlogg. Granted, kinda sucks that sholveware like this is getting one, but those for more popular games are coming too
Only for US, but you can post in it regardless I think. You can access them by changing region at the bottom of the page (was it here before? I think we just got Miiverse updated)
It's like that for every virtual console game that is on both platforms that I've seen so far. I don't know what is keeping them from flipping the switch on letting you post in them properly (screenshots and showing it as owned) from the 3DS as well. *shrugs*
I get the feeling that the Wii U communities will get priority for a while.
It's like they're holding it over our heads that they can obviously launch new communities fairly easily if newly released eShop shovelware can get them this quickly but yet they haven't got their communities for popular first party games up yet.
I'm not angry at them, who knows if they are having weird problems or restrictions, it's just an observation.
Do people not understand it's way easier to add the 5+ new titles this week than it is add the hundred or so 3DS games that don't have communities retroactively...? It's a far harder job than they had with the U.
