Ridge Racer 6 becomes my personal favorite RR game
Ridge Racer 6 keeps the traditional gameplay that made the other RR games addictive. Just high speed, intense racing. The only downfall to the game is that to be able to advance to the next race, you MUST get first place. It can be frustrating, but it's not really that bad. The game starts off fairly easy, as you'll glide through races, unlocking cars left and right, and then, about 100 races in, after spending hours racing already, you'll unlock the Special and Expert courses, adding another 10-20 hours of racing. The game is huge. Over 200 races in all.
Graphics:
Nothing real looking, or amazing, but just sleek and pretty. Definately some of the best on the 360. The car designs are cool and the tracks and backgrounds are beautiful.
Sound:
The announcer is annoying, but easily turned off. However, you can unlock Heihachi to be the announcer :P The music is rave-a-licious as usual.
Replay:
Tons. Have been playing this game for about 20 hours now, and will easily have another 20 to go.
Overall:
A must own racer for the 360. I would even go as far as saying it's the best.
