I mean, FF8 had a giant-ass turret shooting X-ATM, and multiple games had stealth - from Locke stealing clothes to Cloud playing reverse wack-a-mole in the Shinra tower. If anything, they're now in a more direct/visceral (haha, that word) form due to the action-focused combat system.
But we're going down the rabbit hole of derailing this thread with yet another stylistic/gameplay debate. So probs best to leave it at that. :V
I honestly wouldn't expect any FFXV event till the game comes out, yeah. Maa-aaaybe a short teaser event to coincide with Brotherhood or Kingsglaive or something, but that'd be a break from the norm from all other numbered titles that had their main game before any spinoffs like X-2 or CC.
Sorry, didn't mean to derail.
I'm 99% sure there will be an event on release week, probably both versions at the same time. Maybe a ridiculous thought, but that's what I'm feeling.
