Right now I am GMing a Call of Cthulhu campaign for my friends. There is one thing that both me and my players do not like - skill spamming.
In Call of Cthulhu to make your chars stronger/better you have to repeatedly use a skill because a successful use of that skill will allow the player to advance that skill and make it better.
The problem is that the game design kind of forces you to use different skills at any instance possible. My players are aware of that and do not like it, but are still spamming the skills because they get rewards - better skills > stronger chars > more successes ... That results in too much meta-gaming, low role play, use of the same skills etc.
How do I deal with this so that my players would be more encouraged to role-play rather than focusing on finding all the situations where they could just roll a die just to get a skill boost?
