Realisitc Map Limitations

What are the realistic limitations of level sizes for us as map makers?

I dunno map limitations, but that will be found out within the first week of release.
What im concerned about more is the BSP/VIS/RAD build time...

It would be strange if the engine couldn't handle arbitrarily large levels. Barring hardware requirements, of course.

Note that there won't be any light compile times. I don't know about geometry and visibility calculations, though, someone who has tested the leaked editor might want to answer that.

Look at Quake3 Team Arena.
Build times are very fast tho.
