To all of the guys above: well, I love music in my games, I love music even more in racing games, and I pretty much need it in arcade-y racing games. In fact, the first thing I usually do in games is turning up the music volume and turning down the rest of the effects (given that the music is good and greatly complements the experience, of course). As I said, just my opinion.
Edit: I'm sorry that I even started this argument. I was really only meant as a short little side note.
What's really important is how fucked the online part of this game still is. I actually have the game on my desk, still wrapped in plastic, but I don't have a PS4 yet (I purchased it during a sale). I was really looking forward to playing this game once I finally get a PS4 in the near future but now it's sad to see that all of my gaming friends are about to sell the game because of the online issues. Plus: none of them even knew about the stuff that will be patched/upgraded in the near future (weather, tracks etc.). All of this makes me wish they would've delayed the game even further in order to deliver a more refined product. First impressions matter and Evo completely botched this part.
