DM of several campaigns, including a West Marches D&D 5E sandbox. I really enjoy people being creative and as a DM try to reward that wherever it makes sense, instead of shutting it down and railroading.
I love a good mixture of RP and combat, and love it when things get dangerous. A beloved character may die, but the best memories are those of the times you died heroicly or managed to save the day while overwhelmed.
