Hmmm ... that's a good question. For $100, assuming $50+$5 for the game box and shipping which leaves $45 left over ...
1) 3 smaller figurines (pewter, doesn't have to be painted) of either ships or individuals of the races.
2) 11"x17" Poster depicting Sins: Rebellion logo plus awesome battle scene that could be signed by the dev team / StarDock support team?
3) A numbered certificate that states what production number your boxed copy of the Collectors Edition is. It does NOT need to have a xxxx out of xxxx stamp, just a 'This is Collectors Edition Box xxxx'.
How's that sound for $100? I would like to see something along those lines for $100.
Minus the figurines and throw in a car/computer case window decal with the Sins Logo for Rebellion instead and I'd pay $75.
I really liked the music CD in the last version of the Collectors Edition for Vanilla. I'm not advocating that it goes into the Rebellion Collectors Edition, but it would be nice to see something like that as a purchasable item through Impulse.
Just some thoughts.
