That's just the way internet arguments tend towards minutiae. The size of grass doesn't matter. Comparing the photo to the game, the game obviously doesn't look like the photo, in so many ways. It is the same track layout and general design, but it's far, far from photorealistic. So when GTFordGuy says, "Exactly there are parts of the track but the parts in the pictures they've shown look the same in real life," some will find cause to criticise due to the ambiguities of the phrases 'look the same'. And the previous term 'good'. Meaning different things to different people, we get these rather silly debates.If we're down to discussing discrepancies in the off track undergrowth, Turn10 must be pretty spot on.
All of which comes from someone putting photographs in with F5 screenshots! Whoever joined those images together (T10 or Gamershell) is responsible for having T10's computer game compared to real life and come out looking rather disappointing.
