Digital distribution of games means that no game should be preordered. Ever.
Back in the day, a preorder was done to get the physical media (cartridge, disk, CD) in your hands on release day. The premium was either paying for early shipment, or ensuring a copy was reserved so that you could pick it up on release day.
Then digital distribution meant that you could buy a game and be playing it in minutes. When there is no physical media, there is no need to reserve anything.
The industry responded by turning preorders into bonuses. But almost universally, these bonuses are not worth the premium. They tend to be a single mission, or some custom skins, or other items that were relatively cheap to produce and that serve only to justify charging more for a "preorder" on a product which is distributed digitally.
So:
Is Ace Combat 8 (Deluxe) worth pre-ordering for ¥11,990?
Negative. And neither is any modern game. If you want to play a game, wait until it releases and buy it.
Let the concept of preordering die.
