Yeah - Car Wars was my jam back in the day! 
I kinda bounced off of DND but got super into the Champions and Traveler RPGs back in the 80s.
I just recently picked up the Star Trek Duel sets from way back yonder on Ebay - that's some quality nostalgia gaming..
Couldn't get anyone to play Traveller with me but did have a character created that with GM approval and cooperation on the back ground could have had fun with things that could throw the other players for a loop.

My Marvel Superheroes character drove the other players a bit crazy especially after the GM started adjusting the strength of defenses based on the nature of attacks and my character (Darkling) was elected leader (which he didn't campaign for). They even threatened to hang him right after he saved the entire group and they left him alone in the collapsing underground lair of the villain.
My gaming group ranges from hundred to thousands of miles away and others who by their actions make their company unwanted. Unlikely to find another I'm afraid. No windows systems so computer gaming is pretty much out.
My employer is shutting down at the end of July so my lucky streak has ended. It'll be hard to find another job at my age and I'm really not ready to retire.
