To be fair, and I bring this up any time someone lists player count, significant drop off - especially for single player games - is the norm. Even many beloved games drop to very low numbers. Now, I'm not saying this data is useless; it is hilarious how badly some of these failed, and they absolutely did. There's no excuse for Redfall, for example. And I haven't followed Payday 3, but that looks like a mess just looking at those numbers.
