| Barozi said: pretty much every current gen game sold worse than its predecessors on week 1. The userbase still isn't there. |
Maybe you're right that the lukewarm sales of Mass Effect Andromeda (it probably did fine with digital) and other sequels are due to the still limited userbase. Though, many games have been performing quite well this gen. So maybe it has something to do with franchise fatigue and quality decline of said franchise as well?
If one of my favorite publishers, Sega, somehow gets a hit on their hands this gen (Persona 5 or Sonic Forces?), literally all prominent publishers have experienced sales successes and records in recent years (and that's even without a single Call of Duty game). As a bonus, many of these games are truly amazing as well. So all is not bad
