Shameless Cash Grab
Please correct me if I am wrong as I do not wish to start an unfair attack on this game. I've been a big fan of the Ticket to Ride game from Days of Wonder. However, I am really disappointed at the attempt to milk people in this game.
Basically, it is impossible to "own" this game. Battles will cost you coin, and after finishing the initial 50 free coins, you are offered the opportunity to buy "more coins" but not the actually game! That means if you really love this game, it is possible that you will have to buy coins for the rest of your life just to play against the computer or online players.
There is a good chance that I might pay 10 euro for this game. However, judging from its business model, I think I will uninstall it afterI finish my free coins.
