Larian Studios Forums Divinity: Original Sin 2 Divinity - Original Sin 2 - Suggestions and Feedback Suggestion on races:

Really happy lizard race is in the game, as far as I can tell it's quite unique to the game, I'd like to see more unique races, suggestions:
Dendroid, like in Heroes 3 and so on, or LOTR.
Insectoid, there's plenty of rare cool looking insects around.
Octopoid, like in the Pirates of Caribbean.
Something like a Minotaur just with a different animal or even a bird.
I've been googling and came upon a pretty cool page for ideas:

Even if it would be difficult to implement now, think about adding it to Original Sin 3, which I'm buying even if(especially if) it's a recycled game(mechanics) with new adventures.

They aren't adding more races. It's a lot of work to get all the reactions in place. Undead is the only one coming. They especially don't need to add in brand new races never before mentioned anywhere in the previous games.

I don't recall Lizard race being mentioned either. I'm just saying, for future games if there are any and I hope there are, I'd like to see more races.

Lizards were in Divine Divinity, the first game, and Dragon Commander, the... fourth game.
