Day 21 - Favorite Licensed RPG
You probably think I'm going to go with Buffy and that was my initial reaction. However, I'm going to have to go with DC Adventures.
Next to D&D and Cinematic Unisystem, Mutants and Masterminds is my favorite game. DC Adventures uses its system. DC Adventures is my favorite licensed rpg because it's my dream rpg. You take my favorite supers game and mix it with my favorite comic universe. That's taking a win and covering it in win sauce.
I also appreciate that DC Adventures was one of the last pre-New 52 mainstream continuity books.
