Like you, many of us posted tons of ideas about what we would like.
Zup said he'd love to read it......so I guess that's cool.
Most helpful I found his comment on some ideas, for instance the two-seaters or bombers.
Multiple people in one plane, cause lots of lag. Sending all the info of where the plane is, and those players are, to other players on different locations in the world at the same time, with different internet speeds and such incomprehencable (is that correct?) stuff is hard to realise. As I understand it, the server can't guesstimate where all those players are.
I would love to read his or others (who know what they are talking about) explanations of what ís, and is not possible....so I could fantasize and share useful ideas.
The game is evolving again,......since we love it so much, that's pretty exciting!
I would suggest one thing: REALISM
(Combined with perks like eternal life in the form of respawning and such.......)
