Dragon Quest XI S will also arrive soon on Xbox One, PC and PS4, but there are no discounts for those who already own the original game.
Square Enix has in fact decided not to offer no discounts on the title coming out this December for owners of Dragon Quest XI, as well as did not want to opt for a DLC upgrade. It will therefore be necessary to pay the title at full price.
In addition to this, it should be remembered that Dragon Quest XI S will arrive on Xbox One, PC and PS4 as direct porting from Nintendo Switch. It will therefore be content better than the basic version already present on the platforms already mentioned, but graphically lower.
However, remember that this is an excellent title, especially in its updated and revised version.
