[Developers] Computer games not released on a specific platform

[Philip Kendall]

Hi.

I'm trying to get a list of computer games which *weren't* released on a
specific platform, but I'm having trouble formulating the query. I've
tried:

[
  {
    "id" : null,
    "name" : "Double Dragon",
    "type" : "/cvg/computer_videogame",
    "versions" : [
      {
        "platform" : {
          "name" : "ZX Spectrum",
          "optional" : "forbidden"
        },
        "type" : "/cvg/game_version"
      }
    ]
  }
]

which I hoped would exclude /en/double_dragon as that was released on the
Spectrum, but it obviously isn't. Is there any way to write this query?

Cheers,

Phil
