Don't worry, These Are the Voyages was the only episode that Riker was playing in the holodeck. You can tell because of Star Trek's rule that there are no external VFX sequences or establishing shots in a holodeck program or dream sequence. If you ever see spaceships from the outside then you can be sure that it's something that's actually happening... unless it's in Lower Decks, which has the holodeck switched to cinematic mode.Yet another reason I don't rewatch ENT unless it's on the Pluto streaming app. The revelation that it was all Riker's NPC bingewatch ruined the whole thing for me. We do the bingewatching, not them.
