Just playing Universe SandBox and accidentally plunged a giant tennis ball into saturn...so an army of giant tennis balls?
The last thing I wilfully killed in a game was Tropico 3. The civilians weren't happy so I declared martial law, the rebelled and I shot them. So I guess an army of civilians? I prefer the army of giant tennis balls though. I could start an interstellar tennis tournament and charge for entry. After it becomes big I can sell TV rights and other coverage, even have counties bid to hold the event. Then I could bid on it myself, hold it on my Tropico island and then the civilians might be happy, just maybe.
