Ya from what I heard they're prerendered maps, rather than procedural ones created on the fly. Was kinda disappointed in a way, judging from the graphics I thought they had the ability to mix-and-match several prerendered sections together. E.g. urban, throw in a random carpark, a building or two, some walkways, etc. Didn't realise each and every single map was fully prerendered. I'm also interested in the weather/lighting aspect. It'd give more options to carry things in your inventory like night vision scopes or whatever, then later on combination stuff to reduce the number of things you'd want equipped, etc.
