Campaign Character Creation Settings

As many of you know DM's have rules when creating characters. "No Goblins" or "Start at level 14" are a few examples. I present the request to customize character creation within a Campaign.

It can be simple to start with the DM selects which features are on or off. Once that phase has settled in over time the on to the next phase.

Phase two would be limiting races classes spells and other selection within character creations.

But the final phase IMO would be advanced character creation - such as higher-level character creation (including starting gear) and Custom Ability Scores systems (custom point buy, 4d6 reroll 1's, etc...).
