I am putting this thread back in the main forums so that everyone could discuss what should be not allowed in the Roleplay. Here are some Roleplay rules that I got from a wiki (Credits at the end). Fell free to discuss and add your own. These rules will be edited to fit our Roleplay later on.
1) Godmodding
Godmodding is when a character features god-like abilities, such as invincibility or mind control, or other unrealistic powers that don't fit with lore. It's also considered godmodding to refuse death in fights or ignore role-players in scenarios in which said role-players are attempting to attack you. Nobody's good at everything; try and keep yourself in check.
2) Overpowering yourself or others
Being "overpowered" is more or less what it sounds like: giving something or someone an unreasonable, unfair, unrealistic, or unbalanced amount of power, especially when it interferes with the ability of players around you to have fun. This can apply in the obvious ways, like having a character who is invincible or can summon the wrath of an army with a flick of his fingers, but it can also be more subtle.
3) Metagaming
Metagaming is when a player applies OOC-retrieved information to their IC character, such as participating in a war that you only saw was stated to be happening on a faction's thread on the forums, or hearing whispering because you saw the text, and knowing a character's name because you saw their username. This is the most commonly broken rule of role-play and most infuriating for many.
4) Mixing IC and OOC
Related to metagaming, it is considered taboo to "mix ic and ooc." That is, players are generally encouraged not to associate information and events that occurred between active, playing characters and events that occur between the role-players themselves. Most often, when players associate OOC information with their IC behavior, whether it be how they percieve another character or actually acting on information they wouldn't otherwise have, it's called metagaming.
However, it's also considered poor form to take IC information and apply it OOC. That is, if character A insults character B, and player B takes character A's insult as a personal attack from player A rather than exclusively an IC attack on character B, that is mixing IC and OOC. Any instance of holding against a player what his/her character said or did violates this rule (not to be confused with holding against the player any rule violations he made while controlling his character).
Another instance which is less inflammatory but still technically a violation of this rule is if character A says something, character B doesn't understand or takes it the wrong way, and player A deigns to explain himself OOC to player B. This is especially the case when player B already understood but was intentionally allowing his character to mis-react for the sake of adding interest to the game or being true to character B's nature. This cramps the flow of role-play and can sometimes be insulting to a player, since it suggests that player B's character is a Mary Sue who player B can't separate himself from.
5) Lorebreaking and Lorebending
Lorebreaking is when a character breaks lore, which is anything that likely affects a character or scenario. The basis for these commonalities is origin, culture, and known historical events.
Lorebending, a similar term, is when existing lore is lightly modified (Hence the term lorebending), but not significantly or in a way that detracts from the role-playing experience. Often this has to do with ideas that are neither supported nor contradicted by existing lore.
6) Powerplaying
Powerplaying occurs when a player operates someone else's character without the other player's consent. The most blatant example of this would be a player writing, "Your character falls off the cliff when he walks up to it." As you can see, you take active control of what the other character does. Not only is this not fair to the other player, but it's also discouraged because often players will misconstrue the behaviors and personalities of characters they didn't design. Powerplaying goes into more subtle situations, however. Saying, "Sally charges Jack so fast that he wouldn't be able to react enough to avoid it," can also be considered a violation of this rule since Sally's player has controlled Jack's abilities, possibly in a way that doesn't accurately represent his character. The appropriate way to word Sally's attack would be, "Sally charges Jack so fast that it's unlikely he could totally dodge it without equally inhuman speed." This leaves it up to Jack's player whether or not Jack is actually capable of avoiding Sally.
Powerplaying also extends to natural and nuetral forces. A Roleplayer cannot control forces which are not under his direct control.
7) Mary Sue's
A Mary-Sue is a specific kind of character that is usually considered literarily reprehensible and otherwise unpleasant for others to play alongside. A Mary-Sue is any character (of any gender, age, race, or species) who fits one or more of these descriptions:
A character who’s too perfect, lacking realistic or logical flaws, or whose flaws do not affect them in real ways.A character who’s exactly like their creator, except idealized or made “better”. (E.g. more attractive, smarter, given skills, abilities & powers the creator wishes they could have.) Essentially, the creator is inserting themselves into the story, but without the flaws, quirks & limits that make them interesting and real. Users are often discouraged from creating characters who would be described as, "He's based off me," especially since that comes with the extra risk of violating theavoid mixing ic and ooc rule.A character who’s far too powerful, especially whose abilities exceed that which is possible for his/her race in the setting of the story. Particularly if said character has abilities that do not exist within the boundaries of the story’s world. Often these characters are technicallylegitimate, but are very, "Look at how unique and cool I am!"A character who’s cliched, having qualities or characteristics that are overused by people trying to have a powerful/perfect/cool character.
