Sure, it's a waste of time for you if you don't notice it. I don't notice the race time bug because I'm not a competitive player. That doesn't mean there's any reason for me to say it's a waste of time for people to bring it up. It means a lot to some people.

And there are no end of other bugs. Obviously, as someone who stopped playing the game due to the crashes, they mean something to me.

There should not be bugs. And there aren't bugs like these in most PSP games. So it's not exactly nitpicking.

As for the sound, personally, I feel sound is hugely important. One of the most defining WO moments for me is hearing the roar of the crowd on Altima for the first time. It felt huge. Sound makes the atmosphere. That's the big deal.
