While I tend to gravitate towards RPG, FPS and (resource gathering) RTS games... pretty much the only genre I don't play is grand strategy games or 4xstrategy or whatever it is called (Paradox strategy games, Civ series, Master of Orion/Magic etc.). Not that I wouldn't want to, but they just feel so overwhelming when I try to play them, casting you to the deep end of the pool right in the beginning.
I much prefer how e.g. resource-gathering RTS games slowly introduce you to the game, starting with the basics and mission by mission moving to more advanced and challenging stuff. Learning by playing, no need to even read a manual.
It is like with music, I listen to pretty much any genre... except jazz. I just don't get jazz. Jizz jazz jozz. Is it even music? Sounds more like random notes and sounds coming out of a noise box.
I'd almost say that I don't listen to hiphop either, but then once in a while I hear something that I like, like this old classic:
