Add Default House Rules to GM Guide

[LockerM]

Provide a section in the GM guide with a list of a few house rules and ways to make judgments/rulings within and without the house rules to give GMs more leeway at the table. We might expect each table to organically develop their own house rules, and can plan to add more over time that the Community comes up with that they think work really well at their table.

Can refer to other rulesets' use of House Rules and what does/doesn't qualify as needing to be addressed or included in them.

I'm thinking of various House Rules that could be in play and the different scope it could take. Some house rules are discrete or small:

• cover works like this
• in dim lighting these additional effects take place
• when drawing Target Cards you may or may not allow the use of Fate Cards, etc.

Other rules I thought of might be a bit more game-changing so it's worth a discussion of if/where we might put them.

• Perma-death: if a campaign or table does not want characters to die permanently, the GM can implement a feature known as "The Temple" which is a place where a Player Character can be resurrected by their party members. This can be optional entirely, can have a cost, can require an entire sub quest or additional Adventure, but gives a GM whose table does not want permadeath the ability to still have punishing/challenging combats but not TPK their table permanently or have one player die and get upset/quit on them if the players all decide they don't want permadeath. Other RPGs are extremely punishing so this might be good for less intense players, and it might be good to make it an optional house rule to add it rather than have it baked in and then a table as a house rule needs to remove it.

Additional House Rule as proposed in resolution to #101 as merged in #142 is regarding diagonal movement.

You could alternatively decide that players are
limited to 2 diagonal moves per round of combat, or that a diagonal move is worth 1.5
speed.

Additional House Rule to resolve #107:

• The number of Free Actions used in a single combat turn can be no more than 6 (1 per second).

[LockerM]

Additional House Rule to resolve #81:

Limitations or standard type of respeccing on level-up

Cynical take: This is a list of rules we don't feel confident about and encourage variations on.

Not opposed to the strategy, but perhaps context that will reshape our approach to this list

Based on previous comments and ideas represented in here my proposed resolution is for us to simply add a note in the GM guide encouraging people to modify the rules as they see fit to fit their unique needs and the goals at the table. I think until we have more players and GMs running this regularly we won't know what to establish as a 'default house rule' versus just giving them the rules as written and seeing what does and doesn't get modified.

Separately we can work to address in specific setting guides other ideas or rule modifications we choose and showcase how people who write their own adventures can modify the base rules how they see fit.

Attempted resolution will be part of next PR as part of this commit: 25ecd79
