(This page is based off a list that I swiped off an RPG tips site. The original was written by Jack Butler (who has a neat superhero-based PBeM webpage). I modified the text to suit my purposes for Ground Zero. The original list was a bit pedantic, and it still might come off as snarky. Don't worry - I'm not a hardass.)
Ten PBeM etiquette tips for beginner players. Follow these basic rules and, generally, you can't go wrong:
The most important tip is the final one: remember that it's only a game. The whole point is to have fun.
Yes, this is simplistic. So what. Make sure you respond to every move, even if it's a quick note saying "I don't really have something to do so I'll just do research". There is nothing a PBeM GM hates more than setting up the game, sending out an exciting and gripping move, and then receiving no replies. Your character isn't going to be center stage all the time, but when he's not you still need to let me know that you are still interested in the game.
There will be times when life prevents you from posting. Maybe you and your family are going away on a trip. Maybe you're in the hospital having a baby. Maybe you're flat on your back with pneumonia. If possible, always warn your GM about times you're going to miss posting. If you can't warn him, send an note fully explaining why you missed responding to the game as soon as you are able. This is polite, and might save your spot in the game.
There are several different types of posts to be wary of, each with its own problems:
Say "Behzed does this", "Behzed does that" (if Behzed is your character), "he bravely attacks", and "he runs away, screaming". Avoid speaking in the first ("I do this" and "I do that"). And don't write "I did this" and "I did that".
The primary reason is because the GM will write the moves in third person, present tense. When he tries to integrate your responses into my moves, and you've been writing in first person past tense, the tense and perspective clash. Making life easy on your GM is a good thing.
Regardless of what language you are writing in, choppy paragraphs and badly constructed sentences make for difficult reading. People won't read your posts, or respond, if they cannot decipher what you write.
When presenting dialog, use the correct punctuation to help identify how the dialog is being heard by others. It varies from game to game, and GM to GM, but it's almost certain that there is going to be some accepted rules about dialog conventions. Some conventions used in Ground Zero are:
"Use quotation marks here," the speaker said aloud.
<I speak a foreign language,> said a voice in perfectly accented Ancient.
{Squiggly brackets are used here,} the man thought to himself.
(Italic parentheses are used for out-of-character or rules-related comments.)
Most Game Masters are willing to listen to opposing opinions, but please don't present your opposing opinion to them on the game's mailing list. And if a GM ever says something along the lines as "my decision stands", let the issue go. Continuing to argue after he's reached a final decision is not a smart thing to do if you intend to continue playing in his game.
On a related note, don't be a rules lawyer. Most GMs hate this. If the GM makes a rules mistake, politely inform him of it out-of-game and hope he doesn't repeat it. Do not demand that he reverse himself, especially if he already made his final decision.
If you're naturally quiet and generally only post the minimum amount to stay in the game, try to post more often... at least enough to be recognized as being around.
If you're a big talker who responds to everything vaguely connected to your character, shut up once in a while and let someone else get a word in edgewise.
Reply to a new move in a timely fashion. Sure, it's sometimes impossible, but at least make the effort. It also means avoid spiraling time scales. It is rare that an action CAN and MUST take place at such and such a time and no later. If you can do something later and thereby avoid wedging in an unnecessary action now, you'll be the GM's friend for life. The game cannot move forward if everyone is always trying to get the last word in. Don't do this if you can help it.
This rule reads: "If you become a problem, you will almost certainly be removed from the game". This means be polite. It's not that hard. This has nothing to do with what your character does with the other characters. It involves other real people and whether or not they're enjoying the game with you in it. Be considerate and polite whenever possible.
This is the most important rule. No one is going to come up with a cure for cancer while typing away at a PBeM. And PBeMs don't promote world peace. They're just games.
This has three meanings:
(So far we haven't run into any etiquette problems in Ground Zero. So have fun, and game on!)
