5 stars: Amazing game. It's actually easy to reach Antartic War without paying any money into the game. Just collect all medals (try to get 4-5 stars in each mission) from the earlier campaigns for upgrading the financial center to at least lvl 3, and buy a tank general (if you're not so keen on playing the game, G. Vatutin, but if you're keen, you could go for Guderian/Rommel). The other upgrades are not as important as the generals.
5 stars: Awesome strategy game Huge distraction I get no work done around the house. I've played strategy games most of my life and this is up there with the best. Sure you have to spend some money but I've never owned a quality game where you didn't. Back in the day, computer games were $30. to $40. So I'm happy as a camper.
3 stars: I want to love it but can't 1st of all its way over priced. You can't do anything after the 1st set of missions without more help. You have to buy generals which are super expensive. The grammar sounds like they used Google translator. This could be the best game on my phone but to much holding it back. I love the ideas behind the game with picking generals and having them fight with you.
3 stars: Listen. Listen. I love glory of generals. But I think its a money trap. It really isn't playable unless you shell out tons of cash. I understand the game developers want to make money, but if the want to make money, and make the players happy, then they will cut the prices of things, and make it a little easier ...
