It could definitely use more...but the stress that would add to the PS3/360 would be too much.
Do you enjoy talking out your ass?
Maybe it'll stress the Xbox 360, but I doubt it.
I know for a fact all interiors are active on PS3 but glitches are required to enter them.
As for adding activity markers, no stress on the system at all only the cloud server.
That's rich... an apparent PS3 fanboy tells me I'm talking out the ass then declares he knows things for a fact.
If it doesn't stress the PS3, it's not gonna stress the 360. They are near identical except for a few minor nitpicks (i.e. PS3 has better texture optimization, 360 has better window reflections & palm tree alphas)
I wasn't talking about activity markers, I was talking about having dynamic clubs and dealerships the OP referenced. Learn to read. It's obvious that adding a marker isn't going to add stress to anything, not even the cloud server, you genius. If it did we wouldn't have the cluttered mess of markers we currently all have. It's a simple 32x32 wtd.
Having dynamic night clubs, actual dealerships and such is going to stress the online servers as they have to process much more info, hence why we buy cars on our phones instead.
