Rogue is one of the most influential games of all time. Even if you haven’t played it, you’ve definitely played several games that have Rogue’s DNA in them. It became so popular when it was released for UNIX-based systems in 1980 that it created its own genre, which we still know as ‘roguelike games’. Even in the decades when these games were niche experiences, the genre was important. The action role-playing game Diablo built directly on the roguelike genre, which means that all the games that followed in Diablo’s footsteps also have their roots here.
