Homebrew notes

 Time Period:  This fantasy setting will be set in a time period that is relative to the 11th century within Europe. All technological, philosophical, and political advancements will be tacked to this period in history.

 Party: Everyone is allowed to have their "cool thing" about them, that must be discussed with the DM. All party members must be aware of each others goals and backgrounds, as well as having a reason that you are all working together.

 Goals:  This game will be playing in a more sandbox-y way. While there is an overarching story, you may choose to ignore it and forge your own path. The story and choices will be driven by the players, and the players will have to weigh the consequences of going down one path or another.

 Phone Policy:  Texting and calls are fine so long as they're not overt or distracting. Screwing around on your phone for any length of time beyond this is prohibited.

 Goofing off:  Having fun is the entire purpose of this game, and all matter of jokes and other humor is more than welcome. However, you must still actually play the game. If the game stops being engaging or enjoyable and this is the only way you can keep yourself entertained, please talk to your DM about what you want out of this game and your expectations. Otherwise, extreme goofing off will result in PC punishments.

 DM Supremacy:  While DND is a game based around a set of rules, it is up to the discretion of the DM what rules are to be followed, and what ones to ignore. It is okay to point out what decisions violate rules, but harping on it is not.
