I still dont like the idea of having no manual control over any of your walls, heres what i was thinking.
Why dont you just limit the amount of space, and area in which there buildable? I mean wall segments arent all that bad if they have "drag and stretch", I.E. you place one wall, and drag your mouse out and loads appear and you can bend and twist and turn them wherever you want.
I still think its incredibly restrcting.
Ok another question, what if you want to build and entirely new base in another part of the map? Are we only allowed 1 base?
I say give us a toggle for offline...at least.
Otherwise i guess i'll have to attempt to mod it my self :P
