You choose between House Lannister and House Stark. I knew I wanted Lannister, because I love them and feel they (except Joffrey) get a lot of bad press simply because the show made viewers believe they were supposed to side with the Starks. Although things have grown more complicated, it's almost like we were set up to see the Lannisters as the "bad guys," when they're no worse than the Tyrells or Baratheons. Besides, there are worse people, like the Boltons and Freys.
Anyway, my husband loves Arya, so that was fine with him.
