What changes to games would be fun, to try at least once?

Like in chess, if you can kill your own pieces, and maybe go through them to the other side?

Or Monopoly where you can declare that you will rob the bank. Roll a twelve and get $500. While if you roll a two then you go to jail for three turns.

Also in Dungeons & Dragons I am proposing that you need a high of intelligence/wisdom to have access to your character sheet? As one needs insight into one self to know one’s strengths and weaknesses?
Humor welcome.
