Transformers: The War for Cybertron

From what I understand, the overall story of the videogame differs from the canon of the Transformers origin story. As a fan of both Star Trek and Star Warsfranchises, I've run into many canonical issues time and time again (how does one explain Star Tours anyway?), so I can understand the frustration of Transformer purists out there. But if you decide to pass this game up because you can't get over the fact that Megatron turns into a tank instead of a gun, you're doing yourself a disservice -- War for Cybertron really is a lot of fun to play.
