Are they a stupid prop, though? I always thought they looked pretty futuristic. And certainly the real game they are is ubiquitous enough to not be recognized by the majority of viewers, no?
Certainly not the worst prop ever. It was indeed most likely obscure enough to not be recognized by most people (outside of Japan), but those buttons, especially the D-pad, instantly remind me of a Game Boy or Playstation controller which makes that thing look outdated and too "real." One would assume there are more sophisticated toys in the 24th century.
