Yeah, the idea of graphical updates to TBP caused a huge stir in the community, which resulted in the project leader alienating the rest of the team, who thought that supporting a mod for graphical updates, like FS2's mediavps, was a good idea. The project leader didn't, and wound up angering the admins, his team, and the devoted fans.
He's made maybe two posts since, and that was a while ago. Actually retooling the campaigns would probably be a bad idea with TBP. The fact is, we could start what happened in, like, February all over again. Don't get me wrong; it's a good idea, but TBP isn't ready for it. Besides, TBP isn't THAT old.
