If you're determined to buy a Simbin racer, you might as well buy this one.
I know there will invariably be people out there who actually like outdated graphics and crappy physics, so naturally Simbin will continue to sell games and continue to keep re-releasing the same one over and over again. The unwarranted hype alone sells these games, since every idiot on the planet with a PC and a racing wheel thinks they're a real driver if they can pilot this piece of junk around the track. So if you insist on giving them your hard-earned money, I recommend buying GT Legends. It is definitely the most compelling installment in the Sports Car GT/GTR/RACE series (you have to love how they keep changing the name of the game to fool you into thinking it's a new game). It's also got the coolest cars of any of the games.
I know, I've bought and played all of them. The graphics are pretty much the same throughout all of the games (dating all the way back to 1999), as are the physics. You might as well save your cash and only buy the game once. Don't fall into Simbin's trap: when you see their name on the game, you know that you're buying Sports Car GT all over again.
