Is there any chance you'll be doing sceneries for FSX? MAIW and some of the ACG sceneries don't play well together.
At this time, its hard to say, our main scenery guy only does FS2004 stuff at the moment and our current infrastructure isn't really set up to develop for both sims, will that change? I'm not really sure, the time investment just to get stuff out that will work with FS2004 is massive, if you were ever given a peek at the staff only "in progress" forums you'd probably
but heck, I didn't think we'd be around this long so who knows what changes or sims we'll expand to.
