Poll is multiple choice, pick any or all which interest you.
All-Out-War (AOW) - Normal Renegade X as you know it with a time limit.
Marathon - Normal Renegade X as you know it but endless until base destruction.
Infantry Only (IO) - No vehicles and just infantry, time limit debatable, base destruction enabled. (There are at least 3 other infantry only maps with the exception of Valley which have never been played, please do not base your interest solely on the experience of CNC-Valley.)
Sandbox- building damage locked, you can spawn anything you want using a simple console command and go nuts on any map you wish to play, a variety of different mutators can be enabled.
Custom Map Game (CMG) - A place to test upcoming maps which are currently between works in progress and to be released as well as playing standard Renegade X games whilst discovering any issues in the maps before they are released 'officially'.
Deathmatch - Non-standard Rengade X game, no base, no purchase, just spawn as a unit from either GDI or Nod and kill one another.
I am very interested to see what the playerbase is interested in.
Personally I think the current amount of maps open a few doors for server variety.
With a bit of server owner cohesion and shared interest a bit of variety in the server lists could be possible. (Wishful thinking)
