The game had several copy protection layers. Other than a then-standard CD check, one layer would prevent playing a match for more than one in-game year in the case of a pirated release detection, while another would delete all saved games after 8 hours in the same scenario.
When attempting to set the advertising target to something other than Earth (like Alpha Centauri, for instance), a window will pop up saying that it's not possible in this version of the game.
In the North American release of the game, waitresses have a sprite similar to female temps, differing only in a darker shirt. All other versions have a unique, more "appealing" sprite.
