good concept, management of resources and even storyline. Like the quests. Cannot, however, stand the constant attacks inside the vault. They serve NO purpose, nor add to the storyline, could tolerate them if not for the sheer number, 11 attacks in one hour. This makes the game not fun, adding to the fact that while an attack is ongoing you cannot assign any dwellers duties. If i'm spending all my time repelling attacks, i cant play the game. not enjoyable, so time for a new game.
