This is something I really enjoyed doing in Tribal Wars, king of the hill. It's pretty much the same concept as the Digiex Picture War, cept you don't need a picture. I will claim the hill, then someone will do something to me, and claim the hill for themselves (often involving my death/booting off the hill). Then someone will do something different to them and so on. I walk onto the hill proudly, and stand there looking cool I claim the hill.
