Black Ops 7 sold less than half as much as last year’s Battlefield 6.
That's definitely a mistype - the previous CoD game was Black Ops 6, and Battlefield 6 was made by DICE and published by EA. Still, makes a good segue into how Blops 7 (which went all-in on AI) compared against BF6 (which released more-or-less AI-free, going by DICE's own comments).
In terms of sales, Blops 7 sold 63% less on launch than Battlefield 6 did in its opening week, earning Battlefield its first sales victory over CoD in both series' history, and breaking a streak of #1 sales CoD had held since 2006.
On Metacritic, BF6 got "generally favourable" critic scores in the low-80s, whilst Blops 7 hovers around the 67% mark. The user scores are much more favourable - whilst BF6 is hovering at 7/10 as of this writing, BO7 is currently at 1.6/10, beating the notoriously maligned Modern Warfare III to become the lowest-rated entry in the series' history.
On OpenCritic, Battlefield 6 earned a "Strong" rating on all fronts (83% top critic average, 90% Critics Recommend, player rating of 90) whilst Blops 7 got a "Weak" rating (65% top critic average, 35% Critics Recommend, player rating of 20).
Overall, signs are pointing to a historic victory for Battlefield over its long-running rival in the FPS genre, and a very public rejection of AI slop in all its forms.
