We could make a scoreboard for high scores... but it would have to be on the honour system
Problem with making a scoreboard is there are too many permutations. You'd need a different scoreboard for every combination of variations, and each of those for 2,3,4,5, & 6 player games. Otherwise, people who usually play 2-player mega-Carc (like myself and my girlfriend will always top the list…) I mean, I posted
a session report on BGG about two years ago - so without any expansion released since then - with a final score of 397-388. How could you usefully compare that with say, Basic game + 2 river expansions, with 5 players?
Maybe if we worked out a formula which took account of score, players, & number of tiles. But that sounds way too complicated…
And anyway, nowadays when we play we use the tower dispenser to shorten the game. All the tiles are possible, only half are used. Factor
that into an equation
