Until 12PM EST on December 24, the Humble Store is giving away GRID. GRID is an outstanding game and while it is nearly nine years old, it is still a remarkably fun experience. The AI team-based approach remains unique and it still holds up nicely visually and thanks to the many racing genres represented. It’s a finely-crafted game and its overall campaign approach was actually the best one of the bunch in the GRID series thanks to its sponsor and team setup. Its rewind system became a genre staple and allows you to make a mistake or two without being punished severely by having to replay an entire race. When it was first released, it was worth its full price tag, and at free, it’s a no-brainer.
