5 stars fo how good game is but - 5 for developer's greed they do not care about you , I wish I seen someone post like this my advice is good game till you get to headquarters 30 then to get anywhere you will be tempted to spend , do not fall into that trap!!!! I really feel sorry for new players that do not read this I really hope you do, don't even spend on small bundles that's the start of trap if you like it play it but please do not spend as to will never catch the big spenders.
