posh-adventure is a game for bored sysadmins. You are Sir Nigel Fawlett, and you have an appointment for tea with Lord Trealey. Of course, it’s not as easy as simply walking from Point A to Point B. This is the first (or close to the first) RPG written in PowerShell. It includes leveling, combat, and even multiple endings. Windows-only, of course, developed for PowerShell 5.0 but might run on earlier version.
