Monopoly Junior works like this already - you MUST buy a property you land on, if you can't buy it for any reason the game ends.
It really works when playing with kids, but I noticed that the consequence of it in most games is that the player who goes first usually wins.
> the player who goes first usually wins
That is the point the game is meant to teach. Literally.
The original game developed by Lizzie Magie is a didactical game to illustrate the problems of monopolies accumulating ever more wealth.
It is crazy that we seemingly forgot the message and keep playing this game. Even on a purely “is this fun” level there are so much better games.
I got that message loud and clear when playing this the first time.
