NetHack

The most popular roguelike by any measure. A undisputed classic in the realm of adventure games. NetHack has it all. An immense challenge, indefinitely replayability and incredible depth. You'll spend hours getting to level 10 and you'll long for more. There were rumors circulating that nobody has ever beaten it but I can testify that they are untrue. As a hint try being a Valkyri first, they are by far the easiest class to play. You can play it instantly via Flash based Nethack
