Anti-Monopoly. Yes I know how much they are worth now. I think we sold it (sister actually) when he had a house closing sale (and it along with a lot of my childhood marched out the door).
Hero Quest : My dad and I used to play this all the time. He didn’t really like it, but I loved it so he put on a smile and played it with me nonetheless.
The Grape Escape : Now this game was cool. I loved grapes and I loved squishing Play-Doh. Wikipedia seems to think it should have made me into a psychopathic killer, but I never progressed past serially decapitating grapes.
Mouse Trap : This game was so fun, but so very frustrating. Inevitably, someone would accidentally bump some part of the contraption or hit it with a die and the whole damn thing would come crashing down. Still, I remember being a little kid, constantly setting it up and triggering it over and over. Man that was fun.
Ditto.
Huh? They’re worth something now? Well, crap.
Loved that game- so many pieces, such a long set up- excellent play.
The Farming Game
My grandparents lived in the Yakima Valley where the game is set and bought me a copy when it first came out. I little while back I found that it was still in print and bought a copy. My wife and her friends thought it was great fun.
I also bought a copy of Careers and was very disappointed to find it had become much more “kid-focused” than the old '60s version my parents had.
Space Hop? Did anyone else have Space Hop? That was fun. You rolled a die (or two? Yeah, I think there were two) and if you landed on certain parts of the board you had to, for instance, “hop to Venus.” There were questions to answer–some of which turned out to be bad science. If you answered right you got to do things like send opponents to the other side of the universe from their mission completion spot.
I was entirely too fond of a Battletech game called Interceptor. Got a computer version years later, played the hell out of it. It wasn’t even challenging any more, but still I played it.
Some of these are pretty non-obscure (Mousetrap? Hello?)
I have played The Farming Game, Scotland Yard and Dark Tower, and my grandparents also have a copy of The Uncle Wiggly Game, although I’ve never seen anyone playing it. And I’ve certainly heard of Advance to Boardwalk and Anti-Monopoly.
We used to play Save the Whales, which was a cooperative game where you worked together to save as many species of whales as possible. O, Bowhead Whale, why did you cost 7 survival points?
True, working versions of Dark Tower supposedly fetch a good price on e-Bay. If you just want to play…

It’s just as I remember it.
Remember Bing Bang Boing?
ETA Here’s a cool link with many games etc.

Wahoo. It was kind of like Sorry!, but with a cheesy Native American theme.
There was a series of small portable games from TSR, similar to Steve Jackson games. I played them to death, but Wikipedia and the web is very sparse on details of any of them…they were little games with paper boards and cardboard counters, and many were very well designed and fun.
Vampyre (my favorite, you play a hero from the Dracula novel and try and kill Dracula)
Revolt on Antares
Saga (viking heros trying to kill a dragon IIRC)
They’ve Invaded Pleasantville (body-snatcher alien invasion in a small town)
Was it Super Spy? I recall my brothers playing that one.
We had this version of Park and Shop. We bent the rules a bit – we picked our favorite stores to patronize rather than drawing cards randomly. The game stopped being fun about the time my brother Mike realized that the way to go was just to select seven destinations that were right next to each other, as opposed to shops that matched our interests (magazines and toys, drugstore/lunch, department store, etc.)
My dad’s mother and sister periodically cleaned out their basement and unearthed such treasures as Cargoes. I’ve always loved geography, so I enjoyed just looking at the map, as well as playing the game.
And predates Sorry! by four years.
Yeah, but we soon had to cut up ballons for the humdrums.
Ever see this DIY? I wonder if you could adapt some PVC pipe…

Marvin the Moon Man – so obscure I can’t find it on the internet.
I had Green Ghost. that was a LOT later.
Ran across that while looking to see if the humdrum covers had a proper name. 
Perhaps you mean Melvin?
That’s it! Wow, what a trip down memory lane.
And here is Camp Grenada.
Yeah – it just hit me that I’d gotten the name wrong, looked it up, and found the same page.
Still have it – rolled-up board, cage dice, and all.
Here’s the Board:
