You need to refine your searches.
Try TDM, DM, Family, Life, City, Knife, love, Trench, RP, RPG, Mini. I think that should create a more balanced load.
Also, I have noticed the decrease of good servers, and the increase in RPs. Unfortunately, the increase in RPs are from te creativity of new players and their lack of knowledge of eventing, and the general dearth in interest to learn. I think we need to just influence the older players with good servers to stay, and tell all the starfish "older players" to go away, because I think it's also the slightly less new new players, like 20Ks, that are better in games, like TDMs, than the new players, that then are mean and bully the younger players, leading them not to broaden their game range. I think for now, anyone who has a popular server needs to listen to server guests as to which admins are and are not being good admins. When bad admins are gone, and good admins installed, then the games are more inviting for new players. Otherwise, they'll just crawl back to their Family RPs, Life RPs, free builds, and other more creative and less combatant games.
