Aw, isn't that a nice nostalgic touch? Dragon Quest XI: Echoes of An Elusive Age will provide players with a cool little bonus in the form of a free Dragon Quest VIII: Journey of the Cursed King costume. According to Square Enix, you'll find this outfit in your inventory when you start the game, and it'll give you a defensive boost when equipped. You'll even be able to upgrade it later on in your adventure.
If you're unfamiliar with the costume, it's what the hero from the aforementioned Dragon Quest VIII wore. Speaking of which, Dragon Quest VIII was the last mainline Dragon Quest title to release on PlayStation platforms here in the West, and that was back on the PlayStation 2, so we suppose it makes sense to have a throwback that veteran fans of the series may recognise.
