And then some GMs ,may say jumping into the water isn't in the rules so it won't work that way.
In fact, the water makes it worse! Like splashing water on a grease fire. Or like when Brad Pitt kissed your hand and then poured lye on it.That isn't a matter of game design or rules systems. And a DM basing his decisions on "logic" could very well say it doesn't work that way, simply because, in fact, not all itching agents can be removed with simple water.
Some players, and even some GMs, hide behind rules. The article doesn't really address that problem, and I'm not sure it should try, given the topic.
To me, computer games have taken the debate out of this topic.
When it comes to tight, clearcut rulesets...you can't beat Computer Games and MMOS.
The only real place that RPGs have left to compete is around the DM. The interaction between DM and player is really the core of Pen and Paper, and its the one thing no computer game has come close to mirroring.
So I agree with Monte, successful modern gaming systems need to pull away from rules and more towards freeform interaction.
