Race The Sun is a welcome fresh take on the endless runner genre, but unfortunately it doesn't really do enough to justify its $10 price tag, particularly when there's a perfectly good version of the game (not to mention dozens of robust competitors) already available for free. Sure, it's elegant and it looks nice but it's also a relatively simplistic score attack game that gets old pretty quickly.
So don't pay £6.99, then. Pay what you want, starting at only $0.25 for a DRM-free download or $1 (64p... ish) for a Steam code! Ta Gooner.
