Its a great game, with great graphics, good mechanics, & lots of room to advance.
One of the reviews I saw called it a "money grab".
Well, how else are the devs supposed to eat?
Id much rather have the option to pay in game (which, while itll take longer, its not impossible to get expansion packs & play free), then deal with constant ads.
