I think--these days at least--that racing games are more than an on the track experience. Even this thread is pretty much about waxing poetic about the games' visuals. I would have liked to see the type of customization we see in Forza. I know it was mentioned that the developer wanted to avoid obscene designs, but is that really a problem in Forza (I've never encountered it)? And, if it is, surely there's a good way to find and discipline those designs.
I am also disappointed at how disconnected the player is from the stunning looking environments. the reset timer should be done away with or made an optional feature.
Lastly, and I may be the minority on this, I would have liked to see an exclusive focus on sports, super, and hyper cars. If we can only have 50 cars, why not make them all elite driving machines? I think it would have given the team more time to include non European makes and a vastly more interesting lineup of cars. Exotic cars racing in equally exotic environments would have made for a great pitch.
I really want to like this game (watching the stream as we speak), but I really wish there was more to like.
