maybe add planets and objects you ca buy to start a colon on a planet that mines its resources. maybe even palns to be able to build your own spacestation
could add upgrades like auto cooker, second employee that takes orders and a machine that givs each customer a drink or snakc to make them feel better after getting there pizza
make it so the idea thing only gives you a recipe that you dont know yet and it has longer recharge and i agree with liverguts idea and you can put elements in the world to affect another like put a zombie disease or zombie in a city and oyu get zombie apocalypes (or left 4 dead XD)
good trick just make a team with yourself assighn yourself to labs without making any games go watch youtube or sonething else in a new tab wait a ong time and your investigatiion should be high recomended you it a long time choose wen u wanna sell ur first game
