Games are patched, films are recut and albums are reissued, yet the review published at release usually stands unchanged. The reasons are practical rather than principled.
The economics point the wrong way
A review published at release captures the concentrated attention of people deciding whether to buy. A revisit published a year later reaches a fraction of that audience.
The work required is not proportionally smaller, since assessing a changed version means engaging with it properly again.
An outlet allocating limited staff time compares that against covering something new, and something new wins nearly every time. The revisit is the first thing cut from a schedule and the last thing anyone asks for.
A review is a dated document
Criticism describes an encounter between a work and a reader at a moment. It is not a specification that can be corrected when the object changes.
Editing an old review to reflect a later version destroys that record and confuses anyone trying to understand how the work was received.
Most publications resolve this by leaving the original intact, which is defensible and also leaves incorrect information in circulation.
Aggregate scores create a further obstacle
Where scores feed into averages, changing one retroactively alters a figure that has already been quoted and used in marketing.
Aggregators generally do not accept revisions, so a revisit produces no change in the number most readers actually see.
That removes much of the practical point of revising, even where an outlet is willing to do the work.
The scale of change is rarely acknowledged
Some games are substantially different products two years after release, with reworked systems and rebuilt content.
Reviews of the launch version remain the top results in searches, and a reader encountering them has no way to know how much has changed.
The gap between the document and the object widens continuously, and nothing in the system closes it. Search rankings favour age and accumulated links, so the oldest assessment tends to be the most visible one.
What has emerged instead
Some outlets publish separate revisit pieces that stand alongside the original rather than replacing it, which preserves the record while updating the assessment.
Others attach dated notes to old reviews, a lighter approach that works reasonably well for small changes.
Neither is standard, and the result is an archive where the age of a review is the single most useful thing to know about it and is rarely displayed prominently.
