From my understanding Naruto Shippuden: Ultimate Ninja Storm 3 + Hyperdimension Neptunia Victory + Darkstalkers Resurrection are not confirmed, it is mere speculation that they may come especially now that many are turning to digital.
I'd be interested in phantoms for Atelier Ayesha, Darkstalkers, and Dynasty Warriors. I've already preordered Neptunia CE and I'm not really interested in Naruto. How much would a phantom for those three cost?
Personally I the two games you excluded were the ones I really wanted haha. Honestly iI would want at least one of those games in the group as I don't really want multiple accounts. If it comes to a point where this group can't be filled, I'll probably just wait for cheaper slots or when the physical release is cheaper.
There are ready to buy open spots for Atelier and Dynasty warriors, though on separate accounts.
Phantoms are 8.33 each for Atelier and Dynasty but Darkstalkers will probably be $10.
Are there any Naruto Ultimate Ninja Storm 3 groups forming?
There is no group yet for just the game. Mind you that the game may not come to PSN as there is no word or hint.
