Today is day 3 of 3 back-to-back-to-back days of D&D. Sunday we finished a two-year campaign for 'Tyranny of Dragons.' Monday I DMed for my office game, which plays roughly monthly, and it was our third session. Today I'll DM the 66th session in my 'main' D&D campaign as they are entering the home stretch of that campaign.
I've had a lot of fun these three days, but the truth is that this is a lot of D&D and I can't say I prefer it to, say, having a free evening with Katie.
