What should I purchase Forza 3 Ultimate or Forza 4

I've played GT5 to death and since I haven't got around to Forza recently, I was wondering which would be the better buy? I'm not looking to purchase any DLC's and I really don't play online.

Forza 4 was just better overall.

The Witcher 2 is cool, I have Forza 4 it's pretty kick ass, so many games not enough time...:(

Idk, maybe go with forza 3 ultimate.

FM4, better driving mode,loaded with content and honestly a better career mode and online :)

Forza 3 was ahead of GT5, Forza 4 was miles ahead.

Well forza for is a better and more refined version of Forza 3 both graphically and gameplay wise + it has newer cars and better online so unless you plan to play the games in order id just get Forza 4.

Thanks for the input everyone.

Forza 4

I would vote Forza 4.

However I heard many people complaining there wasn't enough new content? Can anyone give me some insight on this?
