What are RG's?
/Edit: Ah, Recorded games ?! What do you mean by more detail or efficiency?
If in a 1v1 a 3rd Player was observer you can watch from obs perspective. So that's good, showing you both players. Otherwise I believe that the Voobly Balance Patch 2.0-Recorded Games all come with an automatically added Observer-Player for that matter, which does not spawn and has no influence on the maps. I believe they made it work with custom Random Map Scripts.
Also they have added some Chatcodes for Observers which actively participate in a game, allowing for them to see resources or technologies being researched if they query for it in chat with !t or !r or something.
