I cant say ''per year'', but a least a month or two per campaign, when I'm getting bored with the adventure (as a DM, I already know the ending, and I my monsters keep losing their battles! ). After that time we usually go back or start something new if my players lost their motivation for that campaign.How any times in a year do you take as step back from the DM chair to recharge your batteries and play instead? I'm taking the month of June off. My campaign is starting to get on my nerves. Best to take a step back and come back to it later.
