Star Trek Online follows is one that assures there's always something happening. No ships are just idly floating about waiting for another urgent mission. That's where the new events system detailed in the latest Path to F2P blog comes in. It's a dynamic set of events and missions for players to take part in for a limited time, ranging from pure combat encounters to more social challenges among cadets and civilians.
As the blog outlines, players will be given access to a calendar showing the in-game events planned for the next 48 hours, with other special events popping up and leaving on a less regular schedule. Players can queue up to take part in these events as they become available, giving an alternate path to the extant missions and episodes. It's a fairly involved system overall, and it's the sort of thing that could help convey a sense of a dynamic universe.
