Both and neither at the same time.

All brothers are sons.

Checkmate.

They're not mutually exclusive ideas. Why isn't there an option for both?

@damodar: sometimes, you have to make a choice

Obviously both and neither, game looks great no matter what. Racist.

Brothers from another mother?

They are the same person.

They are Soylent Green. YUMMY!

You do realize that they can be both?

Well, going by how people are usually brought into this world, they are most likely the sons of somebody.

But maybe that's the big twist?

@chrismafuchris: I choose fear.

Other, where other is both.

Because you can't spell other without oth, and you can't spell both without oth, therefore Show Me The Results.

I really thought they were conjoined twins at one point, but then i saw gameplay.

they're sisters

@theht: you can't spell brothers without "others."

They are androids.

No "Brother, motherfucker" option? You are a bad, bad man.

E: This poll is dumb.

What is the name of the game?

Right.

Por que no los dos?

Why do they have to be mutually exclusive?

They're brothers from another mother.

This poll is really dumb. Is is that hard to understand the basics of familial relationships?

I'll go for option d), as in, where's ze Quick Look?!

Well, if the title is to be believed they are brothers.
