This is certainly a slooooww-paced game. Many of the tasks take hours to finish: pregnancy, kids growing up, training dwellers' stats, using radio to attract dwellers, exploring outside the vault, etc. I actually look forward to raiders' attacks, radroach attacks, and fire, since they seem to be the only excitement in the game. Can those accidents occur simultaneously? Because I haven't seen that happen. Even that gets boring after a while. You put 2 or 3 dwellers with shotguns near the vault door and that pretty much stops all raiders' attacks. You put at least one person in a single room, one armed person in a double room, or 2-3 unarmed person in a double room, and that pretty much takes care of roach attacks and fire. And here's my major hint: since raiders' attacks always start at the ground floor (i.e. top floor), your dweller-defender cannot be working on power and water. Fighting the raiders will slow down whatever they are working on, so it is better to be the least important work, i.e. food. In other words, put your diners and restaurants nearest to the vault door, and put your power and water stations underground. But anyway, as I said, this game is too slow and doesn't have enough excitement so I may have to give up on it soon,
