The game seems to download data in the background but I cant tell how much data it is.
Since I am on a metered Internet connection and have about 10GB left until the end of the month I have to keep an eye on my updates and downloads. The game installer was about 80MB which is something I can live with. But as soon as I started the app I noticed a download progress bar at the top pulling data very fast. However, I could not tell how much data that would be. If its a few hundred megs, I might give it a go but it its significantly more, I might wait for the next month to take this game for a spin.
