NetHack

The Good
Its easy with its own complexity, fun and relaxing yet gets the heart pumping. The outcome of the game is the same but the gameplay is usually unpredictable due to the randomisation of the placement of items and monsters.

The Bad
The game only contains ONE objective: to get the gem. The animal that follows gets in your way. The animal the follows you steals the good things such as goblin or hobbit corpses.

The Bottom Line
Nethack is simplised solo game not to much unlike World of Warcraft. You stroll around a dungeon, getting stronger as you kill more monsters and are faced with even stronger monsters. HOWEVER the game has an objective; unlike World of Warcraft, to collect the Gem of some wizard and return it. The objective is simple but the journey is not.

The downside is there is only that one objective
