I don't think other games played a big factor at all. BF1 had been out almost a month at the time of that weekly update and the numbers were pretty much unaffected during that entire time leading up to the update. You're dreaming if you think a cash grab like SRL with everything behind a paywall will entice players to return. IB Rift this week along with Deej spending 2 paragraphs in yesterdays TWaB begging people to make more friends is just validation that the game is dying. They are trying to have the remaining people reach out to others so they don't leave too when they see their friends list's drying up.
