Recommended if you don't mind P2W games.

A mobile port with a bit of a twist. This is very much a typical base management game with PVP and lots of in-game purchases. If you like these types of games, this one isn't bad. It has a bridge constructor mini-game, lots of buildings to upgrade, incremental improvements to unlock with research and lots of events to keep things interesting. You can enjoy for free, but it's a play for little bits at a time over months and months kind of game.
