I don't understand why everyone seems to be putting some form of limits oh\n
the space. I think that 3D seems the only alternative if we are to display
this in any visual form but to use a model like ringworld or a sphere seems
to be too limiting. Wouldn't a form of indefinite 3D space seem more
appropriate? The use of multiple groups to create a 'universe' or a single
massive 'space' could be a local ption driven by the client. Is there a
reason for limiting the space to a particular dimension that I am missing?
