For anyone that owns Forza 4 (full retail version) or Forza Horizion, Forza Rewards is now out of beta head over to this site:

http://forzamotorsport.net/en-US/news/Forza_Rewards_launch_announce

Click on the link and collect your first rewards (the link works best in IE).  Its open to anyone that has a XBox live account (no Gold required).  I'm 4th tier and my first rewards where two cash prizes and two unicorn cars the 1969 Ferrari Dino 246 GT in Horizion and the 2002 Nissan MINE'S R34 Skyline GT-R in Forza 4.

i am tier 3. it says i'm playing since 2007 but in reality i play since first day of the xbox release. maybe because i changed my name in 2007? i also got no points for forza 2 and driven miles and stuff like that. what the heck?

and damn i should really own horizon and i could be maybe a better tier even without the missing forza 2 points  

I pretty much got all the points for Forza 2 and Foza 3 only missing a couple of achievements all my Forza saves are on the same HDD.  So what kind of rewards did you get for being tier 3.  I'm sure they are going to add a couple of more tiers when Forza 5 gets released.

€dit: misunderstood your question lol

edit 2: we got the same rewards but are a different tier lol?

I got 465 out of 500 points in Forza 2.  895 out of 1,000 points in Forza 3.  1,2338 out of 2,000 points in Forza 4 and 1,226 out of 2,000 in Forza Horizion.  I think the only way to reach the top tier is if you actually buy some of the DLC for Horizion and Forza 4.  I'm pretty much contend with being tier 4 I'm sure I will get something decent again next month.  I'm guessing I might have gotten some more cash then you did.  Also you can earn immediate rewards by increasing your tier too bad I only got one more tier to go.   Anyway the Skyline for Forza 4 came in real handy since it helped me unlock the Unicorn Hunter achievement.

Cool. I don't have Forza 4 anymore but I still have Horizons so I can get the rewards for that.

I'm guessing you will get the 1969 Ferrari 246 GT also.  They will probably have different prizes for different tiers some month from now. 

Just a quick update. Still tier 4 and this month I got two more unicorn cars the 2002 BMW M3-GTR for Forza 4 and the 2002 Honda CRX SiR for Forza Horizon. Two regular cars 2010 Ford Shelby GT500 (FM4) and 2009 Mercedes Benz SL65 AMG Black Series (FH) and 20,000 credits for each game.
