Depending on the makeup of your group, it can also make people stop coming to your game.
I've felt that flip side too.
I very rarely get a home tournament game now, as everyone I would play with before are happy to cheat or argue about the rules, and have an anything goes policy, which I refuse to accept now I have seen the light.
Good news is my room mate as developed a good understanding of the game, and we get some good heads-up sessions in now and then, which is far more fun then having to go over the rules twenty times to some idiot who wants it is way all the time.
