Ok this is for everyone who said they wouldn't buy GT4 if it had N2O because it is too much like Fast and the Furious or Need for Speed Underground. First and foremost, you are all still buying the game. You would be an idiot if you didn't. Secondly, how bout you take a little stroll out of pop-culture lane. You kids are so obsessed with the Fast and the Furious. I will be the first to say that the last thing I want is for the GT series to fall victim to the NFSU or SRS craze. However that is by far not the case here. The Gran Turismo series is a sim and thats final. They have their priorities. When you look at the video when they use Nitrous, it is very realistic. You hear the spray you see your car excelerate faster. We don't see any arcade blur effects or anything. They did this true to real life. Now back to your obsession with the Fast and the Furious. Why don't stop mentioning that movie, becauseyour just hurting us by bringing its existence back into our memories. While your at it why don't you also take your biased mindsets to a website or book where you can learn something. Nitrous was not created when that movie was created. Nitrous was first used as an engine performance upgrade on planes in WWII. They began experimenting with the use of Nitrous in the 70's. No one at this point was really able to harness the power of Nitrous Oxide in cars. In 1978, and I accentuate 1978, Nitrous Oxide Systems (NOS) was created and they began selling commercial Nitrous Systems for cars. So why don't you stop condemning Nitrous Sytems when they have actually been an integral part of car modification since the late 70's. Finally if you do not like Nitrous then don't buy it. No one is telling you that you have to put it on your car. Also to anyone who says that Nitrous oxide is taking the easy way out, you better hate turbos and superchargers too. Actually you should hate turbos and supercharagers more than Nitrous because Nitrous only gives your short bursts of horsepower where as turbochargers and superchargers are continuous. Hate or Love it, Nitrous is just another aspect of modifying cars.
