"Artsy" as referred to by the common public, is label that implies beauty, depth, and a high brow entry level sure to push away most people due to themes and/or subject matter.
"Artsy" film examples could include; 8 1/2, or Solyaris (Tarkovsky) . But can even include; Requiem For A Dream, or Full Frontal.
This isn't actual fact, this is simply how a lot of the mass public view the term "Artsy".
So, emotional and psychological depth, easy entry level gameplay. Emphasis on experience over control or goal.
I'd say "The Path" matches this best, that or "Pong"
