What can I say? Support a good cause and also get the Grand Pengragon campaign and lots, lots more.
No massive use for these… but bought 'em anyway!
Mothership expansion for me and the interesting NPCs stuff.
I heard very good things of The Chuubo’s Marvelous Wish-Granting Engine, Troika!, Wintherhorn, and Visigoths vs. Mall Goths. Plus The Perilous Wilds is full of good ideas.
