Sam has a good point, the fact that cars and tracks are 'unlocked' doesn't mean they are. For many more traditionally minded games players, it's not their fault it's how the industry has catered to them for years, the point is to unlock the 'power ups'. This isn't the way LFS works, the fact that I could drive the FO8 right now does not mean that I can. I can't, well, almost can't.
LFS is more about what you do once those things are unlocked, in an online environment, as part of a community - a bit like playing World of Warcraft with a maximum level character. The problem is, to start with you dont know what to do with that character except wander around and look at monsters that cant kill you.
More than any other race game, LFS is about just how good you are at racing. Most race games are single player orientated, and so people think they are good because they beat the game - and they drive around in the real world riced up Ford Mondeo's just to prove the point - but LFS will actually test how good you really are by pitching you against other people who actually are, without question, a damned site better than you...
There is no best in LFS, because there's loads of cars and loads of tracks and every one has a master (usually biggie), and tens of thousands of people are around trying to become that master, for one moment, on one server...
It is LFS that is outside of the box. Where other games stop, LFS starts, and what we have here is a conceptual issue where a customer hasn't grasped what LFS is really about and/or isn't interested in what it is about, lets face it, as a single player game LFS definately sucks baboons intimate feminine area.
