Agony Unrated is a re-released version of Agony. It features technical and gameplay improvements (see the details here), but is essentially still the same game and arguably a release, not a separate game - especially considering that it was originally intended to be an update to the regular version by the developer, which was impossible due to legal and contractual restrictions.
Agony Unrated should therefore be combined with Agony.
3030-61478 and 3030-62506 reference the same game, they can be merged. 3030-62506 could probably also be outright deleted as it consists only of a title and description without any additional information.
I just noticed that, after adding a new game from the Quickly add games section, you get a 'Thanks, your edits are now live' confirmation, which might lead to some confusion because the entry needs to be approved first to go live.
I just tried to create a new release for Trillion: God of Destruction because it's going to be released on steam in November, but I'm not really sure how to set the region(s) for a new release. There is no information about regional availability on the steam page (that I could find) and while I suppose that most releases on steam are identical worldwide, there are some exceptions where release dates or availability differed by region.
How should these releases be handled? Should I just assume that every release on steam is international and create a release for all four regions and hope that somebody will remove the entries if they are incorrect, just create one entry for my own region because it's the only one I can confirm, or are there any additional resources I can use the confirm where a game is released on steam?
