"Build a game that stands the test of time as well as Civilization" is a pretty high bar. 1.44 MB is huge.
POOM, the DOOM clone, is a "multi-cart" on the Pico-8 and still only comes in at 1.2MB on Windows. I guess what I'm getting at is, if someone wants a fast-track to meeting the challenge of 1.44MB, make a Pico-8 game.
- now that would be very interesting to see
