The one thing i feel this game needs is more customization allow players to send their own interactions since the current ones get boring after a while and also english is not always the primary language of all players currently in the game.
just 2 quick examples
friendly: you're fun to be around, i'm going to keep you as my pet for the next 24hrs ;)
hostile: your silly antics are amusing, I cant stop laughing at how pathetic you are xD
I doubt this will be introduced but I couldnt help but post
