Like Cameron said, we're really pushing the realism factor. We (Theo, Cameron and myself) have had many, many discussions about what can and can't be modelled. These discussions go back a couple of months. Whenever there is a delay, it's usually because I found another cool feature to add and then having a meeting with Cameron about the possibility of adding it while I do the manual. Some of these systems take a while. For example, the anti ice system took about 2 weeks to code. I've actually been thinking about putting the manual up prior to release. It's still not done but it's getting there. I've done about 100 pages so far with only a few more to go and then checking everything.
