Af far as the 3-way and 5-way actions. There are a few games that would benefit from an strange number of directions.
Like Kangaroo, which is a s6-way game. Up, down, left, right, up left, and up right. Down left, and down right are not proper moves, so it would be kind of cool if they were blocked.
Of course this joystick doesn't seem to have 6-way action anyway, and plus Kangaroo would have been better off as a 4-way game with a dedicated jump button.
