I've been toying with the idea of making a second WWII Pack, this time with a few structures as well. I'll be using more photographic textures though. I've toyed with the notion of updating the textures for the first WWII Pack as well (using more realistic "photo" textures).
I really need to get back into creating media for sale. I have also given thought to a pack of misc. static entities for the Sci-Fi theme as well; with a follow-on pack that contains some animated entities.
I'll be making these for multiple engines, so when I get to a building pack there may be issues with collision concerning the interiors of buildings.
I'm staying away from characters for now, since Jon and Bond have that pretty well covered and it would take quite awhile to get up to their quality. Same goes for weapons, Jake's got that covered quite nicely.
But it doesn't hurt to push out ideas as to what you'd like to see; it only helps steer us towards what we need/want to create.
