Should I buy Arkham Asylum and City for 360 or Return to Arkham for PS4?   I have played all the Arkham games on my dad's 360 (Knight on the Ps4 of course) but now that I'm moving out, I'll have to get my own console (and Arkham games). 
  
  I want to be able to replay all the Arkham games whenever I want, so I know that I'll need a new 360 in order to play Origins, and a new PS4 to play Knight. However, should I purchase Asylum and City for the 360, or the Return to Arkham collection for the PS4? Are the graphics better on the original versions, or in the remakes? Any major differences I should be aware of?
