If you don't feel like spending $US150-plus on a steering wheel controller after already dropping $100 on a video game, you can always improvise like YouTuber chobiglass did. Using a pair of salad tongs, a computer mouse, and a spinning bar stool, they hacked together a pretty serviceable steering wheel accessory for the game, Euro Truck Simulator 2.
The setup isn't quite a simple plug-and-play affair. You'll need to tweak the mouse's sensitivity in order to make the movements of the spinning bar stool translate properly to the in-game steering wheel. But once it's working properly, the clever hack genuinely looks like it makes a game about driving a delivery truck seem like a lot of fun. [YouTube]
