Even though GT5 has more cars I still think that FM3 has better looking cars and a better variety of cars.  Also all the cars in FM3 have fully detailed interior none of that premium vs standard car bs.  Also a lot of cars in GT5 are total garbage since they can't win any races even if fully upgraded that is not a problem in FM3 since any car can be useful in some form especially since it alows engine swaps.  I also think that the track selection in FM3 is slightly better one of the best tracks from previous GT games the Seattle circuit is totally missing in GT5.  When it comes to track selection GT4 is still the best in the franchise.  I also find it a joke that out of the 1000+ cars in GT5 only 17 can be raced motified they could have done a lot better then that especially since in GT1 and 2 almost all the cars could be race modified. 

I'm guessing you missed the Prologue in the title.  It's okay.  Pretty easy to miss.

With the amount of people that this game has been attatched to I think when Forza releases on the Next Xbox it will move consoles. It's no Halo or Killer App but yes I think it is more than capable of moving a respectable amount of consoles. It's an incredibly high quality title with a now very dedicated consumer portfolio. Most fans of racing games would/do look forward to the next iteration everytime a new one is released. The racing genre is still pretty populated and if you combine that with quality then you have a winning formula. MS knows what they are doing. It's the same thing done with GT3 for the PS2.

But it is no GT as far as sales go.

You might want to look up the meaning of Proglue and Demo.

Not quite sure what a Proglue is, but the definition of a prologue is as follows: "a preliminary discourse; a preface or introductory part of a discourse, poem, or novel.  Any introductory proceeding, event, etc.: Appetizing delicacies were the prologue to a long dinner."

GT5: Prologue was an extended demo that sold more than the full games that were Forza 1&2, maybe 4.  So yea, what's your point? 

Demos dont come with 16-player online races withover 70 cars (including tuned cars), 6 tracks, 12 layouts.

Which is why people call it a glorified/extended demo.  And PD made sure people understood what it was, hence the Prologue in the title.  They also did the same with GT4: Prologue.  So, what's so hard to understand about this?

Was this before or after they spent $39.99 on the game?

It wasn't called GT demo, it was called GT prologue. It was also just an introduction to a game that people had to pay for inorder to play. PD pretty much earned what they paid with just the Prologue. It was a fraction; a taste of what the final game would be like and 5 million people flocked their way to this unfinished game.

That is undescribable. That is power.

LMAO!  Before.  GT fans knew what they were getting with this "demo."  PD had done it before with GT4.  And people who aren't normally fans know what prologue means.  Of course, you also had several gaming sites refer to it as such, Joystiq and IGN among them.
