I've asked this question in the past, but with the influx of new readers, it's something that can easily be asked again:
Do you feel more comfortable as a GM, a player or can you easily embrace both roles?
I see myself primarily as a DM / GM, but I've been having a blast when the opportunity to play as a player comes my way. There was a time where I had difficulty feeling comfortable as a player, but I find these days I can embrace it and enjoy.
So, where do you fall?
