I know you guys will probably say to me, "Just model it yourself!!"
I am currently practicing my modelling skills and cannot model amazing structures or anything. But if there is somebody experienced with modelling out there. I would love to see the Comet Observatory from Super Mario Galaxy in Super Mario 64. Kaze Emanuar is remaking Sunshine and Odyssey in the Mario 64 engine but I would at the very least love to see the Comet Observatory in Super Mario 64's Engine. If we could go further, each of the dome interiors would just be amazing! I hope somebody can do this and I am sure many people would be satisfied with such a hack!
