I thought the idea was very good, and it fits what I was looking for, however, any message that is sent in chat, the pl sends the first response used, and this is unfeasible, since players talk via chat.

Achei muito boa a ideia, e se encaixa no que eu procurava, porém, qualquer mensagem que é mandada no chat, o pl manda a primeira resposta usada, e isso é inviável, já que os jogadores conversam por chat.
