I have started on quite a few follow-ups to Chicken Heroics and finished... Almost nothing. I have 3 or 4 half written things on this hard drive. Clearly the issue is that I'm not telling you guys. Once I say I'm doing it I feel like I need to finish. This short expansion is focused on magic, because my explanation of magic in the core book was like a paragraph. Also because Roosters and Rituals seemed like a good title. I can flesh it out to a 4-8 page booklet no problem. Make up some new rules. Add some new spells. It'll be sitting pretty.
