I passed the camera that records the speed in Horizon and my ranking was ~114,000. It told me that I'm in the top 32% of the world. That means more than 350,000 players played the game and passed this camera already (Slade ranking was ~303,000).
If that number was for Xbox One alone I think it is a good number.

I wrote this info to ensure that the total number of players is more than 300k.

I've gotten top 20% on some camera ratings as well. Some I just didn't bother doing much better at  

You like Knack... your opinion is irrelevant :) 

I got top 1% at 252mph, I have been tuning my car for hours trying to figure out how they got the Ultima GTR to 272 mph.

This is why I suck, I never got any speeds like that :(

My top speed is a little over 200.

I don't get the tuning aspect of the game, seems too technical for me. 

Is anyone else here going after the 168 championships cheevo? 

Most game get scores the day of or the day before they come out so I wouldn't look too much into it. Its only worrying if they have reasons they cant the day they come out like Destiny.

In Jaywood's logic.... we trust :) 

Seen about 5 cod trailers in the last 2 days. Haven't seen a trailer for anything else(besides destiny)Hoping to see some halo commercials, unity bundle or sunset would be nice too. I don't watch a ton of tv though.

Edit. As I was typing this a ms cloud commercial came on that was all about titanfall, wtf let's see some halo or sunset od.

You can see how many are on the leaderboard guys, just go to map, go to a camera and press X for leaderboard...Downright is the number of players on the leadearboard..Somewhere around 500k..
