Came here to post this.
This comes off to me as really weird and suspicious. Doesn't Kadokawa own KanColle? I don't think it's a licensing issue.
It's very rare for companies to take off their games from PSN. Much less one that just released recently.
The only decent reason I think they'll do this is if they're porting KanColle proper to Vita/PS4 and they don't want people to buy this so they'll get addicted and pour their money there instead.
I was actually planning to play this one to play it someday since
this reviewed well enough.
