I'm trying to think of more ways to incorporate sci-fi—or at least relatively high-tech—elements into a hexcrawl. A few ideas:

Near-future spaceship: Would justify a lot of high-tech goodies but not for the most part weapons or armor. Space suits could be a bit better lighter and more durable than real-world models (like the TL7 model in GURPS Basic Set p. 285) but limited enough to be primarily useful in specialized circumstances (so not as good as the TL9 "vacc suit" found a few lines down in the same source).

Alien prison transport: Might have a lot of weapons for the guards but exclusively of the "less lethal" variety, which could force PCs who get their hands on them to regularly ask themselves, "what's going to help us more here, a few points of damage or a second of stun?"

An entire "wild west" town: Period pistols aren't such amazing weapons that the PCs would never use anything else after acquiring them.

It's also interesting to think of specific items that could fit well in a DFRPG game. For example, something as simple as WWI-era binoculars wouldn't disrupt the game much but would still be superior to the optics in Adventurers. A more fanciful example would be things like chainsaws and welding torches—they look cool as weapons, but if you enforce practical downsides of using them as such they're not going totally break the game.
