Hiya!
Well, seeing as I was a teenager through the 80's... I think I might do a Zombie Apocalypse type game; no internet, no cell phones, no "computers" (well, nothing we nowadays would consider 'useful to an average person'...if you don't know how to code in Pascal or BASIC, and have a blank cassette and cassette player, you're SOL...

). Then again, no firk ding blasted car alarms either! So...hot-wire away, survivors!
For the added bonus...I'd have a couple nukes having been used to try and stop the spread in the initial first couple days, or people with their finger on the button just say "What the heck...lets do it! Better than being eaten by a zombie, right?...
PUSH". This would let me have not only zombies...but RADIOACTIVE zombies! But why stop there? We have apocalyptic world, irradiated areas with radioactive zombies...might as well throw in some Car Wars while I'm at it! Mad Max...with radioactive zombies.

For the icing, dinosaurs. Why? Who knows? It was the 80's! Radioactive zombie T-Rex herds chasing down the PC's in their tricked out, armoured RV with a top mounted rocket launcher? Hell yeah!
Or I'd just run a regular game of Top Secret. That works too.
