In Derelict, the missions with the Shivans are much cooler than they were in the retail game. When there are tons of Shivans flying around, like when the Nyralathotep gets loose from the docking rings -- you stand a pretty good chance of actually losing the mission, several times in a row.
There's not some Colossus coming along until later, and when you finally get the Valhalla, then it gets injured and you have to continue to take on Shivans in your (frequently underarmed) old, slow fighters. It's a great idea, and when I finally beat a mission it's pretty cool. I don't know how many times I've hit Alt-J with my hull integrity lower than 25%, but you really are like, come-on, when am I getting out of here. It's well done.
