The premium edition numbers are actually softer than I expected overall. It looks like they might have actually contracted on Xbox...

FH5 was playable on the X1 also so yeah, they had more people that could play it on consoles.

Well highest peak was: 273,148

M$ really needs to learn from how they handle Forza to handle Halo in like manner

It will likely peak at the weekend because of the weird release schedule 

Playground Games is a more talented studio than Bungie the original developer of Halo and Halo Studios/343 Industries the current developer of Halo.  Also, Forza Horizon has been more popular than Halo since Forza Horizon 3.

Just started it today and it had 5m players in the first radar control you can choose from on the map.

It will be interesting to see the official player counts because the last game hit 10m players in one week. It seems the lack of Xbox One version really killed the Xbox numbers, despite Steam exhibiting insane growth. 

FH5 released 9th of November and Turn 10 announced "10m the first week" on the 19th. It also released in November and not in May which probably pushes sales as well. 

So yes, no XBO version obviously kills sales but FH6 still looks really strong especially because it still has time and released in May. 

Due to the awesome weather in many parts of Europe this weekend after months of much colder weather, FH6 missed to reach 300k today but came pretty close with 298,985 players
