Make a self destruct button! That way when people through a fit about the updates and start posting on how they are done they can press a button on their base and watch it blow up. All progress lost and it reset to the start.
After the new slew of complaints they may rule it in! Just make it several clicks....are you sure Y/N......Yes are you really sure......Y/N last chance? Y/N Yes = 3,2,1 BOOM!
Exploding your base could be fun... just pay 5000 gold to get a show of your base being slowly overwhelmed by an endless tide of level 1 barbs...
Oooh, this gives me an idea: A 'for fun, maybe?' mode where you can have wave after wave of troops being sent at you; start at level 1 barbs/archers mix, and each wave gets successively harder until you hit Pekkas everywhere... Might be fun to watch/play...
