To your first list, I would add Trivial Pursuit. IIRC, the core concept hasn't changed, though the subject matter of the questions and their method of delivery has changed quite a bit.Some games that haven't changed as far as I know...
Rummikub
Monopoly (if you don't count the many many knockoffs)
Risk (if you don't count the many branded versions)
Scrabble
Yatzhee
The classics:
Checkers
Chess
Go
Backgammon
It's interesting how many of the games mentioned on this list are brand name versions of older games. Statego goes back at least hundred years. Othello is the brand name of Reversi. Chutes & Ladders is Snakes and Ladders. Up above, Yatzhee is the brand name of Yacht.there's a lot of static games out there:
Poker
Stratego
Chess
Checkers
Risk
Backgammon
Go/Othello
Monopoly
Clue
Chutes & Ladders
etc.
Many of these static games are old (sometimes by centuries) games and have either enough time to settle down into their final rules set or have enough variation in them to keep people happy. Backgammon is settled down, the only change being the doubling cube from the early 20th. Chess has regional variations like Shogi, but is otherwise settled down. Everything else is a marketing gimmick.
Go has a lot of variation within it just by changing the board size and handicap.
Of board games haven't changed much in the since they were introduced, but are sill young enough to be owned by a single company, I'd say we have at least:
Trivial Pursuit
Risk
Mille Bornes
Scrabble
Clue
Candy Land
Hi-O Cherryo
All of the above games have numerous variations and cosmetic changes though. I wonder how often a cosmetic change or weird variation puts-off a potential buyer?
