Topic: For fun: What other genres you like to see mixed with 6DOF?

I'm talking about other gaming genres here.
without further adieu, what other genres would you like to see mixed with 6DOF?  (we've got Sublevel Zero which is 6DOF and Rogue-Like)
Personally I would like to see a 6DOF game mixed with Metroidvania (similar gameplay to Metroid and Castlevania: Symphony Of The the Night) but in first person (obviously)

Well, I have occasionally daydreamed about a 6DOF game that's open world. Not, you know, sandbox open world, more like...what's a good example...uh, Breath of the Wild open world.
