Tom Vasel's Summary:
Chang Cheng is a good middleweight area control game - something that really isn't as prevalent in the market - which makes this a good choice for many collections. Replayability seems good with an ever-changing board, and the lack of luck will please many who want to enjoy tactical placement of walls. I'd want the game based on the components alone, but I'm glad that there is a good game behind them, making Chang Cheng the best product Tenki Games has produced thus far.
