Visually, MotoGP 07 doesn't look so hot, even by PS2 standards. While I'm sure my eyes have become accustomed to hi-resolution visuals, there are still things that don't look right. The bikes look okay, though the texture work is blurry. Rider animation is okay, though it is hard to get a sense of someone actually riding. Instead, it feels like they're bolted on. There's a lot going on around the track; buildings, stands - you name it. However, they all feature the same indistinct texture work that plagues the bikes and rides, giving the game a flat, unappealing look.
As far as sound goes, you have engine noise and music. Nothing really stands out about either, though at the same time, it isn't something that will make you want to turn off your speakers either.
