My uncle bet me $50 I couldn't learn Wingspan in one night. He was right, and I'm still thinking about it.
Back in March my uncle Dave handed me Wingspan at his place in Boise and swore I'd pick it up in 20 minutes since I play a lot of Catan. Two hours and three rules lookups later I'd somehow built an egg engine but lost 74 to 61, mostly because I kept forgetting the end of round goals. He still brings it up every family dinner like he won a world title. Anyone got a game that looked simple and then quietly wrecked you on the first play?
