You could buy the $15 Xbox Live Arcade game Virtual On: Oratorio Tangram and play it with a regular controller. Or you could cowboy the fuck up and buy Hori's $323 dual joystick controller designed specifically for Virtual On.

I wasted too many days in a dank arcade that frankly sucked in every respect except the single reason I went: Virtual On. With its dual joysticks, it stood above all other giant robot games.
