Forget about lag, performance benchmarks, whether or not the UI is an improvement or not etc. The game Cities XXL is fundamentally broken because the trading state is not saved with the city. If you trade some tokens with either Omnicorp or another city, then leave your city and return, all your trading sliders are reset to 0. So every time you return to a city, you have to quickly pause the game and set all the sliders correctly again. If you're not only trading with Omnicorp, but also between cities, this can become very time consuming. Previous versions of the game had some problems with trading, but now Focus have broken it completely making the game unplayable.
