Why did the Yu-Gi-Oh! anime change the dueling boxes/tables used in Duelist Kingdom to large platforms? The Yu-Gi-Oh! Duelist manga series depicted the duels during the Duelist Kingdom arc with the players sitting at dueling tables that were surrounded by a box which projected holographic images of the battles, whereas the Yu-Gi-Oh! anime series depict Duelist Kingdom duels on the large field-sized platforms where the players stood a very large distance apart.

Is there any reason why the anime producers decided to make such a noticeable (but non-impactful) change to the way the duels took place?
Sitting down in an enclosed box that displays holograms of a small size doesn't spruce up the intense battle scenes that the manga wants to convey to the audience. Also sketching huge monsters as holograms in manga comics is difficult keeping in mind that the dueling field needs to showcase both the monsters and the duelists. It would take up a large space on the page.

Also when the anime was being created, the emphasis was made to make duels more interactive than just showing monsters screaming. Like monsters could now be launched from canons, Gaia the Fierce Knight could now gallop and much more.
