Exploration of planets is one focus for sure. Finding species of creatures can earn you money. There's fairly complex base building, ground vehicles to race around in, there's some survival elements, there's a trading system, there's a fairly deep crafting and farming system, and a simplistic job board. There is ground and space combat but it's currently not a strength of the game. They added a 20ish hour narrative as of the last update. We don't know everything that NEXT will bring, but you'll be able to go on missions with three of your friends, you can purchase a fleet of capital ships and do something? with them, and beyond that who knows until we get the final trailer and patch notes.
