My brother and I have been looking at the spaceship toys for the new Buzz Lightyear movie for Sci-Fi gaming. He picked some up and took some scale-comparison shots; they look pretty good!
Maybe you're at a space port and you have to apprehend a fugitive before they can make it to their ship and get off-planet?
There are also some drop pods, which would be great for objectives ("get to the drop pod before your competition" type mission?)
Here are the figures they come with:
And then there's the larger ships, particularly interesting to me is this one, the "Armadillo." A little paint, and it would totally work as your crew's ship in Five Parsecs or Stargrave for "defend the ship" missions:
Don't have the Armadillo, but judging by it's size compared to that kid, it looks to be just right.
