A lot of this trailer focuses on the community that has arisen around the original game, which now sports 150,000 golf courses thanks to user generated content. The first game eventually built a following that the developers want to capitalise on for this sequel.
The sequel will include in-game societies that make it easier for players to collaborate, and clubhouses that will improve as you gain more experience. Societies will be a big part of the competitive multiplayer scene.
Career mode has been expanded, and you can now run your own seasons offline, Course creation is improving too.
