Interesting to see so many changes to classes and similar home brew built directly into campaign house rules. Not how I normally do things.

Each game I run has its own house rule document. Some elements are common to all or most games I run, but each new campaign will have a custom ruleset constructed alongside the custom campaign setting.

Further, house rules tend to get added in response to what the players end up doing and how the campaign progresses.

Here are a few examples from my games.

From my current 3.5 campaign (narrative, mission focused, very custom setting):

From a short lived campaign from 2017 (exploration and resource management focused):

from a 2012 campaign (player driven, magic focused, sandbox):

from a 2009 campaign (high lethality, combat focused, ad hoc player formed parties)
