Stellaxy was originally called "Space Game" with a joking running title of "Ecroso Space Program". Then was changed to "Poor Man's Sky" after hearing about No Man's Sky. The name "Stellaxy" was thought up when interest in the game being on Steam started.

If this is something you wish to know, I've made a quick reference chart.
