Override game base classes

[alchemyfool]

Is it possible to override base class like

Verse.Pawn
override prop like this
public PawnKindDef


or
RimWorld.Plant
public virtual float Growth

I understand that if i manage to do something like that i could easily break the game so i would have to be careful.

Depends on what you mean by "override". If you mean do it for all classes that inherit from it in the game, the answer is "not directly, no" but there may be other methods available to you, up to and including overriding the methods of the base class. Also, many of the XML files refer to the class in the def, so if you are looking at incorporating XML modding as part of your class change out, it might be possible for those cases only. In any case, it would probably be better for you to pose a scenario, of what you want to do, and then to ask for recommendations.

public Gender gender;

I want to add "Alien", "Android" and "Piers_Morgan"
