Yeah... according to an article Europa Universalis is going to come to iphone.. that was 2 years ago.
There aren't many game ported directly for mobile, but if you like this type of gaming, you should try Realpolitks Mobile by Jujubee studio for iOS or Android. They released it in the last weeks (July 20 - 27th) and it seems to be a cool and deep game for mobile, especially good for tablets. It was previously released for PC and it offers full fledged PC gameplay. Sounds like a nice port.
Nice necro. I was confused reading that Total War was supposedly coming to mobile, and then saw the post was from 5.5 years ago.
