Q1. A few years ago, steam allowed you to sort tag-based releases (e.g. MMORPG) by release date.
But recently they moved to different model. Consider the MMORPG page:
https://store.steampowered.com/tags/en/MMORPG/
Now you only have “New & Trending” which does not sort by date:
Q2. Any given steam store page has an option called “View update history”:
This data is also provided in your library in the top “What’s New” banner:
But this is only for games that you own.
Is there a way to “subscribe” to the update feeds of a set of games; doesn’t have to be through steam. An external tools/website would work too.
Cheers!
For question 1, click the search icon to show all steam games then sort by release date and filter by tag https://store.steampowered.com/search/?sort_by=Released_DESC&tags=1754&supportedlang=english&ndl=1
for question 2, there is a recently updated section somewhere try this link https://store.steampowered.com/updated/all/
