At the risk of diluting each of these suggestions, here is my wishlist for what I'd love to see surrounding character creation options (in the order of how difficult it would be to implement):
- Body tattoos. Having the ability to add in arm, leg, and body tattoos would be a fun, but relatively easy visual addition.
- Include Variant Human Option (extra feat at character creation in exchange for some ability boosts. Because it is changed from the books already slightly, maybe in exchange for the +2 bonus?). While I'm certain this can be modded in, it seems like it would be worth including in the base game.
- Additional subclasses. Some could make for interesting choices, and would greatly expand the game without needing to change up dialogue options except possibly a couple specific instances (such as a drunken master monk having special responses when drinking is involved, for instance).
- Additional player races. Aasimar and githzerai seem logical, but could even add dhampir to fit the theme. These could be fairly ambitious, I admit.
