Looks like my prediction is going to be accurate, chose around 100k with big drop.
I based this on placing the numbers below the 150k open beta, and actually I'd have said below 100k but closer to 100k than 50k peak with more than 20% decrease. In the poll, I would have said more than 70% decrease if it was an option.
Why? I don't see the game appealing to almost anyone, the only reason it didn't start with Concord numbers is due to Bungie's multi decade reputation and existing hardcore fanbase. If it was a new studio, call it 'Firewalk studios' as a random name, essentially no one would give it a shot. Due to it's said unappealing nature I think retention will be very low. I did give the game a try in the open beta, so I'm not surprised at all about the result so far.
