Experimental how?
Experimental in gameplay mechanics, like Katamari; Papers, Please; or Hypnospace Outlaw.
This could also be experimental in terms of narrative structure, like Virtue's Last Reward, NieR: Automata, or Tacoma.
I don't wanna be the judge, so however you think is fine with me. Please don't just list things. Tell me about your favorites!
