The other day I was thinking about my GM-fu and of course, I always look for ways to improve it by reading blogs, posts here and a couple of other places, and just published stuff.
Sounds like me pretty regularly
My question is when you play, what’s the best quality your GM has? What is it about him or her that makes the game "kewl"?
Hmm, tough one because I don't think it is one specific aspect - I also have a few DM's (play in multiple campaigns).
For me, I feel like I need to keep the group entertained, that's my #1 job if you will - they need to have fun and that requires of me multiple skills.
I'll name one of them here that I feel is very important, but often overlooked...
...The ability to maintain flowing conversations. NPC's know what they know (whatever that might be) and when a PC asks them questions and talks with them, there should not be a lot of "oh's" and "um's" - the NPC's reaction should not be halting or slow to react as I think it takes away from the suspension of disbelief (imho). Good, flowing dialog (to me) shows that NPC's have a life beyond what the PC's see day to day and this makes the world feel more real - players get more drawn in and their imaginations have an easier time of taking over. You can see this in the faces of your players (at least I can in mine) and it's great.
Now, there is a time and place for halting, jarring dialog if that is an aspect of said NPC for example - if they are slow, unintelligent maybe.
This may seem like an obvious thing (flowing dialog), but most DM's I play with could do a lot better.
I'm not perfect, but I'm pretty good imo - it takes a good bit of improvisation and quick thinking and it's something that I really work at.
