Oh I see. But maybe that would be more convenient the other way around :
When host get an "answer" message from peer, he adds a key "CreatureCount//Multiplayer.message" with value "1". Or add +1 to the value if the key already exists.
Then peers score if "HostAnswerList" has key "CreatureCount//Answer".
At the end of the game, the "HostAnswerList" dictionnary should look something like that :
1//blablabla 3
1//bliblibli 2
1//blobloblo 5
...
2//blebleble 7
2//blublublu 2
2//blyblybly 1
...
Which would be cool to analyse.
