I know most fiction works like this, so its understandably tempting to make one character the main character in the campaign. However, it doesn’t work like that in practice. Your audience consists of a handful people in the form of your players. Each of them has a character and each of them feels particularly close to that character. So, for them, your chosen protagonist is just a nuisance that keeps their character from taking the spotlight. Nice job alienating most of your audience.
I used to play with a GM who used play a lot of Nick Cave and the Bad Seeds. Mostly Murder Ballads. I might not like it as much as I like some other albums by them or as much as certain other people I know, but I like it. And there lies the problem.
Okay, this is a big one. Nothing like the previous two, but gladly this isn’t big in the sense that I would need a book’s worth of words for this.
What it boils down to is this: If you are willing, you can put a lot of the responsibility on the players and let them control much of the environment. So, of course, the question is, what happens when your players, who are gamers by definition and as such understand that this can give them an advantage, abuse the system? Well, first, lets recount all the instances this has happened since I’ve adopted this trusting style of GMing.
When your mother dies, what do you do? You have a funeral, you mourn, you’ll visit her grave. What do you do when a player character dies in an RPG? You hand them a new character sheet and leave them to fill it out.
You know the situation. Your characters are facing a bunch of goblins you threw in there just to have a combat encounter, because you feel like you should have one here. And what happens? One of those apparently harmless goblins crits and would deal deadly amount of damage to one of the characters. So, what do you do? Well, okay, maybe you didn’t roll the maximum, maybe he just rolled poorly on damage instead…
You know, no-one’s ever going to know…
