Amnesia - Different Random Events

Unfortunately I don't have enough programming know-how to make my Custom Story "Truly Random" as for example, MineCraft worlds. So to make the players experience as random as possible, maps will be littered with random events. Some events will be more gameplay changing, a handful will unlock entire rooms and others won't make much of a difference but will add variety. Since I am sitting in college with not much to do I thought I would explain these different random events.

Minor Events - These events won't do all that much, as I just said they will just add variety. I'm talking about an event of whether the lights will flicker or books start fallinhg off the shelf. I hope these minor events will add greatly to an atmosphere of unpredictability I am trying to achieve.

Major Events - These events will change the way players tackle a problem. For example there might be two possible events each of which change the way a door is blocked. In one situation a door may be blocked with rubble, so the player has to find an explosive or move it out the way. In the other situation the door will be locked and the player has to find the key instead.

Play-Through Changing Events - These are the big events, they change which rooms the player can gain access.

Each of these events may seem simple and perhaps somewhat boring, but imagine if you were to mix them all together. One room out of three is chosen for you to go, inside that room there are multiple ways monsters can come at you, and get past them. Plus several minor events inbetween make gameplay unpredictable and generally more fun.

I can't wait to finish my demo and see what people think of my creation, so far. :D
