I did take a look over the last couple of months, and I do think that there is slightly more to this than randomness FWIW.
By effectively every public-facing metric we have (such as they are), something does appear to have changed / be changing, even when we ignore 2026 releases (which I think is fair - year is still ongoing, and data in 2025 showed a skew towards releases in the latter half of the year for COG in any event).
Apologies - the below will be imperfect as the inputs were hand-generated, but I think it works well enough to bring things to life a bit - if anyone has better data than me (not a difficult feat!), or data from years prior to this, I’d love to compare notes.
Releases per year since 2018.
Reviews on the COG / HG apps since 2018.
Releases with 500+ reviews since 2018.
*Rolling Total should say rolling avg, oops
There’s a lot of interesting stuff in there (for a massive nerd like me, at least…) IMO, but one thing that jumped out me is that arguably the big 2023 'launches discussed above masked a broader fall-off that took place around that year. There are certainly other ebbs and flows - see 2021, straight after COVID - and of course the late-25 games will be somewhat impacted by recency meaning fewer reviews, but I don’t think it’s wrong to say there seems to be something more sustained over the last couple of years.
I’m not really sure what my conclusions are yet, if any, but I’m curious as to whether anything interesting happened over that 22-23 period. The 19-20 supernova of reviews / engagement also stands out, but is of course easily attributable to COVID tailwinds, so that’s less interesting - just a black swan for all forms of digital entertainment.
Could be as simple as swathes of the mobile gaming taking a hit in general since then, to be fair - I’m not at all certain this is a COG-specific thing.
