Rogue is a better game than most of the bigger Roguelikes that followed it. Character creation is literally just inputting a name, so you don't have to spend eons creating a character who then proceeds to die two levels in, every level is at most 9 room, and there's only 26 levels, so you don't have to dedicate 5000 hours to each playthrough like you would with something like Angband, and the game is mechanically simple compared to things that came after, so you don't need to dedicate time to reading wikis. Not to mention, the lack of meta progression compared to modern Roguelites means that you don't have to dedicate multiple failed playthroughs to getting more powerful, the only thing that changes is your skill and the randomization.
The Doom Roguelike is the only other roguelike I've played that I've enjoyed as much as Rogue.
