While it may be better suited to mobile these days, World of Goo is a great puzzle/bridge-building game with a simple mechanic it explores well.

A seminal masterpiece that took the world by storm with good reason. I spent thousands of hours in Minecraft; a game for me about exploring creativity within tight restriction. Must play.

A fresh, visceral and addictive hyperactive trip of ultraviolence, strategy and style. Finds its rhythm immediately and sticks the landing. Hell of a soundtrack too.
