As far as I know Rogue did fairly well on it's home PC port, where it really got popular and inspired a genre though was on I think unix mainframes, people played it at college campuses and universities in the late 70's into 80's. The much more popular game in the Rogue lineage is for sure Nethack. People just started calling that genre of gaming roguelike because of the original game, no matter how good or bad it was. Rogue is too hard and too bare bones for modern gaming standards, but back then it was something else. It was the closet people could come to playing a virtual game of Dungeons & Dragons.
