10 Incredible Games With Only ONE Mechanic

10. Slapping (Thank Goodness You're Here)

Have you ever had the desire to be a weird little guy running around a quaint English town slapping things? Yes? No? Maybe? Well, if you have, this side-splittingly funny game has got you covered, as it lets you do exactly that. 

Created by indie studio Coal Supper, Thank Goodness You're Here is a surrealist cartoon-style game set in the fictional town of Barnsworth, a silly place full of eccentric people and slappable objects. Your goal is to help the kooky residents with all their bizarre problems, leading to countless eye-watering interactions. 

Mechanically, all you do is walk around and slap things, with the world changing as a result of whatever you've laid your hands on. Hitting one small thing often leads to massive environmental changes, causing a butterfly effect with unexpected outcomes. Baking an enormous pie, uncovering a rat supermarket, using butter to help someone unstuck themselves from a gutter - you'll do it all and more. 

It's one of the funniest games you'll ever play, and it does it all with just one mechanic.
