SPDCA: Another idea for a game.

I like the idea of dealing with special relativity in a video game, specifically time dilation at near-light-speed travel.

I don't know how to make that fun, though. Math isn't fun. Nor travel.

My first thought was an intergalactic grocery delivery service. You need fresh groceries across the galaxy within 1200 years, but it will take a year to grow the delicious fruits and vegetables, and they'll only be fresh for a few weeks.

My second thought was playing as some sort of space whale, that has to keep feeding in order to stay alive, but can travel at nearly the speed of light. So the trick would be to be accelerating, decelerating, and traveling while your space "krill" grows back after 1000 years, and timing your travel such that you never starve.
