Wing IV is fighting a lot of unexciting battles on multiple fronts - loading gameplay scripts to in order to load FMVs you've already seen, which requires loading subtitles, and branching options - which you've already seen but need to be implemented anyway. And then there are tasks like updating the particle editor to make it more user friendly.
And after that I'll still have to update the effect/material editor. That's not even mentioning other boring stuff like task/bug boards, a new server to allow us to use more than the 1GB of assets we were limited to for the demo. We are trucking along; there is just a *huge* amount of boring groundwork to lay.
