Battlefield 1 has almost 1 million active players across all platforms.

Battlefield 1 is, hands down, one of the most beloved titles this year has to offer. It has launched just a day ago for the wide-ranging public and over four days for Enlister players. It’s safe to say the Internet is receiving the game pretty well with startling reviews from big outlets.
From Battlefield 1 stats, we can observe the following active players:
PC: 89,093 (24h peak: 171,382)
XBOXONE: 93,722 (24h peak: 248,449)
PS4: 180,562 (24h peak: 272,844)
Combining the 3 platforms it adds an enormous 692,675 players in Battlefield 1. For comparison: The latest game from DICE, Star Wars Battlefront, peaked at 347,974 in concurrent players when looking at the last 24h peak a day from launch, so pretty much half of BF1.  Electronic Arts hopes to sell 15 million copies of their latest Battlefield entry.
