The entire gaming market is a popularity contest (where the the most popular games win in terms of sales and mindshare).
But the claim that said popularity is solely because of marketing is laughable. The most popular games in terms of mindshare are generally high quality games; often the highest quality titles.
Marketing budgets also correlate because publishers give the biggest marketing budgets behind their highest quality franchises and titles; e.g. Sony's marketing budget for TLOU II was likely multiple times that of Day's Gone. When publishers know they have a winner on their hands they will put their full marketing weight behind it; and conversely, if they know the next game in their series is a dud, they'll spend less on marketing (typically... Of course there are always exceptions *cough*MS).
Alanah's point is predicated on the presupposition that games like Dredge are inherently equal in quality and entertainment value as games like BG3, Zelda TOTK, Elden Ring or TLOU II. The reality is, they aren't and the difference in popularity is a result of the market recognising this difference in perceived quality and entertainment value.
There are many absolutely stellar smaller indie-style games that deserve to be awarded within their own category, but in the wider superset of games releasing in a given year, smaller games like that just don't provide nearly the same level of entertainment value as the best AAA games.
