i think a cool one might be how fast can you just cancel out the 4 default tasks, like you go into freeplay, whatever map category, and from the first input the timer starts and you have to go to the laptop and cancel the 4 default tasks so it shows the end screen(and repeat for 3&4 maps categories). it sounds pretty pointless...and it is...

there's a list in the guides page(for airship - polish ruby)
