Star Trek Resurgence has consistently excellent reviews. It’s about a 25 hour role play where the player makes choices for two different crew - a senior bridge officer and an NCO in engineering. It’s well done and one of our teens and I are enjoying it a lot. Great value for the sale price. My patience on this one was reinforced by its initial release being exclusive to Epic - but on Steam and on sale it’s worth it.
Bridge Crew is an older game. I have had it for a couple of years, and took advantage of the sale to pick up copies for each of our kids Steam accounts. One of them got really into it right away.
Timelines is also older. It held their interest for a bit in middle school but doesn’t seem to be one of the better tie-ins.
Star Trek Online is a long running massively multiplayer game that starts out free but then can cost a lot for in-game purchases. One of our teens is into it, and got fairly far without purchasing much, but the Steam sale is a good opportunity for them to buy things they’ve had on their wish list.
As a parent, I find these better than the endless number of Star Wars mods on Roblox that one of ours got into for a while.
