I don't think that's realistically possible.

Day two on the planet there would be no bases left to cap.

i said i wouldnt mind it

it would be pretty cool though

If you look at some of the Ruins that come with the 40K table top. Many of them are in ruins. The destructible terrain for buildings don't have to be OBLITERATED completely. They could just be skeletal frames, or space metals that survived even the harshest of bombardments.

yeah problem in alot of games is that matter disappear instead of becoming rubble...

But urban warfare is much more fun.

I think that by physics you actually mean character animation. That's huge for me and most MMOs lack proper animation, mostly because of technology limitation, not bad animators or anything like that.

I meant in terms of the engine but yes this too
