Unfortunately there are no great free alternatives to wikia. There is Gamepedia which has less community stuff, but ostensibly they are the same and those recent addition flash popups are huge turn off for me.

Best thing for mid-size established communities is to be hosted on private servers, but that is only possible if someone is willing to chunk out some cash for hosting..
