You wait ages for some pulp Sci fi rules to be 5e-an-ized and two come along at once. The only thing to do is back both. First is Amazing Adventures 5e from Troll Lord Games
And the next is the 5e conversion of Rocket Age...
My first thought is malfunctioning holodecks. Kira and worf in one, Bashir and Garak in another. Some black market dohicky Quark buys causes them to fail and he is brought in when the other complain over minor faults. As well as keeping themselves safe there could be other patrons in danger too.
The third of the Ruins & Adventures series, The Sanctuary is available now at RPGNow. Each one is ideal for dropping into campaigns when PCs wander off track.
