North America release would increase profits.
Instead of removing features from the game, and making the drops worse, why not release the game in North America. A North American release would guarantee an influx of new players, more cash.
At the rate this game is going, all good features will be removed in the name of profit. None of that is necessary, just expand your market. Make the right call, because your fans are watching. Rovio can have a bright future, or no future. You decide.
