some of my opinions to get more people to play is to big tournaments and play the best of the best.......also we could have newer guns and instead of only playing capture the flag most of the time, there should be some new games like king of the hill or free for all or have a map that is completely dark and the only way to see is from a flashlight from your gun like the game "Halo." Another way you could get people play more is to add some monsters like the ones on "Quake" or on "Half-life."
Tournaments shouldnt be organized by dp, they should be a community effort. There have been and will be tournaments, check them out in Clans,matches and tournaments sub forum.
You won't get newer guns, I guess, but the gun models might receive work, so I've heard.
There already are different gametypes, KOTH, dm both exist.
Don't think monsters will appear in dp, but I've heard things about tutorial maps, so bots might have some role in there.
