The game Seaport by Pixel Federation is a very fun “empire building” type game. You are the owner of a shipping fleet and fulfil a series of jobs to ship materials around the world. Over time you get better and more ships, talented captains to lend their special abilities, and explore more of the world to find more destinations for your ships.
There are also special events where you can compete against other players and earn more rewards.
