The reasons for playing Legend of Dungeon are exactly the same that lead us to play other roguelike, the unpredictability of each playthrough and difficulty. We are not always strong, do not always have enough damage or find really useful items that work well with our ideas. There is no way to know how everything will go, and creativity that the game makers put in all the items makes it fun to find out what we will maybe on the next attempt. Unfortunately luck is also a big factor Legend of Dungeon, just as it is in all roguelike. There are some playthroughs where it is not supposed to actually get to the end.
