Video game idea

Does anyone think this would be a good idea...
ITs a FPS massive multiplayer similiar to planetside.
Would involve building actual forts/bases from the ground up.
But could also be destroyed from the ground up. Also would have the
ability to make caves out of rock and such. I guess would be like a
level editor while you are playing, but more in game involved. I think it
would be cool, becuase it would create huge wars to take over or destroy
bases/forts.

That actually sounds like a good idea. I like the concept of been able to build caves and such. Is this something that you are looking at designing or just random thoughts?

I would love to make a mod using either the torque engine or source. I think if a mod is good enough you will be able to make money off it. But if you use the torque engine then you own it and all proceeds go to you. However I think that source has much better graphics capabilities. I dont see a problem with making this, the only major issue is the net code, getting 1000 users online at once is a big task. But maybe having some sort of in game throttleing that involves only letting so many people in a certain area at once may work.
