I picked up Korea: Fire and Ice and South China Sea while I was at the con. I'm happy enough with them having only paid half-price, but I would have been disappointed if I had paid the full retail. The maps and counters aren't great, imo. Definitely not up to a GMT level of quality.
I like that Compass is putting put a wide variety of games that cover many periods, but I'm a little put off by the production value vs cost.
