Quoted from NightTrain:

Ok I'll be honest. I was a Tron hater at first. I heard all of the hype and plated it at the arcade a bunch of times. I just didn't get it. What was so great about this game!?
Then I found one for sale close enough at a great price. I decided to buy it, knowing that if I TRULY did not like it, I could get my money back out of it.
I've gotta say, this game probably isn't going anywhere for a while. Once you get some time on it, you'll understand why so many people enjoy it. I immediately added a shaker motor and an external sub woofer and it made the game even better. The game play is smooth and flowing. It's fast and will kick your ass. The music and call outs are awesome. The DOTS are great. All in all, this game is just a great complete package.
A lot of people are dumping games right now. It's that time of year when people are getting outside and have other hobbies going on. Also, you have Metallica which people are eating up, and Star Trek in the near future. Don't let the sales be something that steers you away from Tron.
If the price is right, I say pick it up!!! This is coming from an ex Tron hater...now converted...
