Question about a past collab

[Risvertasashi]

Ok, so if (or once) FF15 items appear in the Mog Station, then the event may not appear again.

For items that have made their way to the mog station, their event has never once returned - For SE to do so would be unprecedented. So, yes, overwhelming probability is if they go there, the event's never coming back.

Aren't the other Final Fantasy game items on the Mogstation? the FF10 and FF13 ones.
Licencing shouldn't really be an issue for them since it's an internal product that they own.

Yes. But both of those are specific cases, weren't done on the yearly clock. FF10 wasn't even really a crossover event, it was a fanfest thing, and those items appearing took far longer than a year.

So basically, like Rannie says, we're off the edge of the map:

Eh there's honestly no telling so far there have been other se crossover events like the one from ffxi and the dragon quest ones that havent been put on the mog station that I know of... and the quests havent reappeared for them either. *shrugs* They get odd about it at times.
