Feel free to run it after monocon. I'll probably want a break in between that and Seconded! But be wary, while CIW is a simple game in terms of roles, it can be quite confusing to GM. In normal "simple" games, you have few people actually using powers nightly. In CIW, you have everyone using some power every night and everyone who uses a power gets feedback.Ok. I was thinking about running the minigame because it was pretty simple and I could see how GMing is without running a complicated game that ATM would be too much for me.
I'd suggest if you really want a simple game, go to the basics of the basics. Wolves, a seer, and a bodyguard or two. The rest are vanillagers. It's a very easy game to host and can be really fun to play as you can't rely on roleclaims.
