Id preface with that I know it would probably take a WHILE to impliment as youd have to make a whole movement system etc that the twins could actually interact with but given that evil has a 3d model and I presume neuro is getting one at some point It might be a cool idea to have the twins stream in 3d sometimes since they are cool models. I don't know what exactly youd do in 3d with them but im sure there would be new potential content ideas that came with it.
But overall I think it could be a cool thing/consideration for the future if they have the capability to handle 3d movement.
does it.
