But the reason Forza Horizon stands out - not just among the racing games of the last 10 years, but among the very finest video games of the decade - has nothing to do with cars. It is its relentless and inspiring positivity, its generosity of spirit. From its globe-trotting views to its heart-pounding soundtrack, Forza Horizon is all about finding excitement, happiness and beauty wherever you look. This is a video game about joy. What better legacy than that?
