GMing. Without a doubt.

In particular, dealing with fools who think their character concept is nice and balanced and should be approved, when it is blatantly obvious it is overpowered and unbalanced and violates half the lore.

Keeping the plot moving along is also difficult, especially when you've got many players with disparate schedules and the IC plot is chaotic in layout.

What Ellri said, while anyone could technically be a GM. There's not all that many good GMs. Personally, the hardest part with RPing for me has almost always been dealing with people. Those that aren't interested in RPing with me, but claim to be. Those that seem a lot more interested in arguing and starting drama than doing anything else. Lately it's been particularly hard to remain motivated to RP at all, and I've asked myself more than once why I still do it. All thanks to having to deal too much with certain kinds of people or behaviour. I still got that one good fun RP I've been doing for almost a year now, and that seems to be the only reason I didn't quit at some point.

I've been turned off GMing group RPs solely because of the difficulties I've had with running them [i](MIGHT think about it again if I was co-GMing)[/i]. Creating motives for people, trying to prevent powerplayers and dealing with people in general. I remember one time where a player got accepted into a roleplay, but when it came to writing a scene, they converted one of the GM's races from a peaceful race into a group of warlords simply because he did not read the damn OOC!

When things go wrong as a GM, they can sometimes go seriously wrong and you're left there trying to clean up the mess while hoping others won't ditch the RP.


The second difficulty has to be with creating a decent post with good ideas. Generally for the first few pages it's easy, but sometimes after the first Act, so to speak, it becomes harder to think of what your character might do. I'll occasionally get a writers block and it really screws me over because I don't have any ideas that sound decent.
