Bastoche said:"No campaign is COMPLETELY open. The very idea is nonsense."
False. Some games are.
Theoretically you might be right. Realistically, however, there is no campaign which is COMPLETELY open.
For starters, a completely open campaign wouldn't and couldn't have any rules. Rules immediately imply that you can't do something, thereby closing the campaign.
Second, there wouldn't and couldn't be a GM. A GM, in order to GM, must be able to arbitrate actions -- but arbitrating an action means that you decide what happens, which immediately closes the campaign.
And so forth. Such a game doesn't exist. Sorry to burst your bubble.
This does not, of course, mean that the concepts of "open" and "closed" are useless. But it does mean that you need to accept that your personal set of preferences is not the platonic perfection of "openness" while all the rest of us are toiling in the dark shadows of "closed" campaigns.
If you want to seriously argue that the DM, by having it rain today, has "railroaded" the PCs into getting wet, so be it. There's a glimmer of truth there, because the DM has, in fact, made a choice which affected the PCs without letting the players have input. But I find that definition of "railroaded" to be utterly useless. And the claim that this type of gaming is inherently "bad" or that it constitutes nothing but "the players reading the DM's book about rainy days" absurd.
