Both are much more impressive and can be had in the under 50 range (in fact, I believe I only paid 25 for RBR because its an older game).

With its advanced 3D rendering engine and a physics engine that ensures each car has a distinct feel, Redline also shows that running someone off of the road isnt just cathartic, its downright fun.

Gun the throttle, light up the tires, and hurtle down the track in any of the three racing modes Redline offers: the realistic Simulation mode, an aggressive Arcade mode, or kick it into high gear in the insanely intense Turbo Arcade mode.

The real fun, though, is meeting nice people on the Internet and running them off of the road.

Redline supports up to 12 people in a network race, either on a local network, or over the Internet.

Meet up in the Lobby, pick a course, pick your cars, and recklessly slam your newfound friends into the guard rail in your quest for the coveted checkered flag.

Redline models each wheel of your car independently, as well as the axle width and weight of each car, allowing for an unprecedented feel of the road.

Accelerate your way into a corner, tap the brakes, cut the wheel at just the right time, then punch the throttle and power-slide your way to the finish line.

Boooooyah Redline features a dozen racing challenges such as acceleration, slalom, graduating you to real-world tracks with a variety of racing conditions.

Your performance is also ranked among other Redline players from around the world via an Internet leader board.

I like the way high scores are kept on the net and how you play the challenges to unlock cars.

Very cool.

And basically, my conclusion is, dont even bother downloading the game if youre interested in a simulation.
