I found Hacker Evolution Untold to be a fun and interesting game. Those with any command line experience should not have difficulty learning the command console in the game. I've only had my first Mac for six months, so most of my experience with command consoles comes from Windows and DOS, but I quickly adjusted to the UNIX style command console in the game. Best tip I can offer is to read everything carefully. Some clues are obvious and some are not. General rule: If something looks even slightly out of place, incorrect, or inconsistent investigate it, as it may be a clue.
