AB gameplay within Sandbox metaverse

[DreadKnight]

Ancient Beast should be reproduced and playable within the Sandbox metaverse game, especially if we go for the #2022 (accelerator). Link for the Sandbox metaverse game is https://sandbox.game - it's using voxel art and has a nice editor that also supports animations and putting stuff up for sell in their market place and so on https://sandbox.game/en/create/vox-edit

Relies on #1970 to be implemented first.
