As a rule, Star Trek makes no effort to maintain continuity outside of its Live-Action Television series and films — in fact, for a while, there was a directive that tie-ins couldn't reference anything except the live-action canon. Novels, comics, video games, roleplaying games, technical manuals etc. draw from their common origins, but exist largely independent of each other save for occasional Shout Outs or borrowed elements.
There is a modern line of Star Trek novels from Pocket Books which make an effort to be consistent in regards to continuity. Most novels from the year 2000 on are generally set within the same reality. This continuity is discussed on the Star Trek Novel 'Verse page.
Some of the older books have been retroactively absorbed into the "Novel Verse" continuity, most have not.
A new continuity was created with the Paramount+ series:
Other show-specific Novels that have followed the new literary canon include:
There is also the Star Trek Autobiographies series that is its own continuity.

- Star Trek: 25th Anniversary: An episodic point-and-click adventure game featuring the cast of the original series.
- Star Trek: Judgment Rites: The sequel to 25th Anniversary. These two games are generally considered, alongside (or for some fans, instead of) The Animated Series, to comprise the final two years of the Enterprise's five-year mission under Captain Kirk.
- Star Trek: The Next Generation: A Final Unity: The third point-and-click adventure game of the franchise, this time focusing on the Enterprise-D, and featuring the full cast of The Next Generation.

- Star Trek: Starfleet Academy: A space battle simulator using video footage.
- Star Trek: Klingon Academy: A sequel to Star Trek: Starfleet Academy where you play a Klingon warrior. Also serves as a Prequel to Star Trek VI: The Undiscovered Country.

- Star Trek: Away Team: An Isometric, Real Time Strategy game set two years after the Dominion War.
- Star Trek: Armada: The prime example of a Star Trek RTS game. Got one official sequel.
- Star Trek: New Worlds: Trek's second entry in less than a year to the already horrendously overcrowded RTS market of the Turn of the Millennium, focused on planetside colonization. Vastly inferior to Armada, what with it being a Star Trek game largely without starships.
- Star Trek: Starfleet Command: Turn-based strategy starship combat. An odd kludging together of the venerable Star Fleet Battles ruleset and settings with Trek canon. Got a whopping two official sequels.
