If you have a bottomless checking account, this is the game for you
It started out all too well; a promising turn based game with WWI aircraft. Select your pilots, upgrade them with bonuses and new aircraft. The first few levels were fun, so I decided to continue and finish the current campaign, thinking $4.98 for the nation packs would be value for the content received. How wrong I was.
As others have said, the difficulty level spikes almost immediately after the unlock point. The game becomes frustrating and no matter what difficulty level you play on, you will lose pilots and lose them frequently, its unavoidable. If there was a way to recruit new pilots to replace injured ones, this would be less of an issue, however the only way to heal your pilots is through a $0.99 cent in-app purchase. In other words, users have to pay in order to continue the game that they rightfully purchased.
This kind of behavior sickens me; insidious microtransactions and in-app purchases are forced on a user to continue to play the game in order to make money for the developer. It is equivalent to highway robbery; and I urge all users to stay away from this game at all costs.
