Kinda meh game if I have to be honest. I really just played it for the gems, if I have to be honest. It's probably one of the easiest games for gems. It's kinda like Clash of Clans, if you know what that is. Upgrade things and battle. Not nearly as much waiting or pay to win, though. You have oil, diesel, and something else (I forgot), you convert oil into the other stuff, you idk with it. There's also a bank where you put moneys in and get slightly more moneys every day. I don't even know why I'm doing this, this would probably get 0 gems if I wrote this as an article anyways
