Review previous games

Along with all the information about previous games it would be great to be able to do a play by play review of the entire game.

This should be doable with a system similar to PGN or FEN in chess. It would also be ideal if the review board could be highlighted with circles, arrows etc. similar to how most chess websites allow for "drawing" on the board (see image attached). This would allow for a better way of learning from past games. It would also enable people to share games with each other, either cause they won in spectacular fashion or lost to a double monopoly play.
