Dunno if it actually needs to be said, but on your profile Reviews page, you can click on a game's boxart or title above the boxart, for quick access to that game's store page. Then, assuming no errors, your review will be at the top of the game's review section, for editing or deleting.

This is a welcome improvement. I hope GOG can keep momentum on site and catalog improvements.

A couple next step for reviews:
* Remove it from unnecessary products like bundles/editions.
* Merge "edition" reviews into "these are reviews for the GAME". (DLCs can still have separate reviews)

Why? There can be reviews of the whole bundle, or reviews that take into account features that only exist in certain editions.

No, bundles should not be rated. They're just a compilation of games and reviews belong to games. The only thing there is to say about a bundle is "price".

And there SHOULDN'T be ANYTHING that exists only in a certain edition. (DLC reviews can cover that.)

The fact remains that there'd be no way for GOG to do that, dev accounts being generic. And it's not like devs couldn't make separate non-dev accounts to review if they want to abuse the system.
I'm glad it doesn't have images. If something specific is needed, could upload the image elsewhere and link to it. And for headers you can just use bold and/or underline. True that it doesn't allow linking within a post, but you can put chapters into different posts (there's a 10k character limit on posts anyway) and use the first one for the table of contents, and you can link to posts.
So if you're looking for a review of a complete or whatever edition of a game, like you're going to play it, you should look for a separate review for the base game, not including DLCs even if they add to the main game itself and aren't separate things, and then for further reviews of each DLC separately, and put them together in your mind?
And what if something is only available in a bundle?

Let me quote myself...

Minor but persistent annoyance: If you only want to rate a game, but not leave a review - and for any game you rated in the past without leaving a review - every subsequent visit to the game page will have the giant "Add a review" box sitting at the top of the reviews. You can "Cancel" it to close it temporarily, but it'll be right back on your next visit.

That is for every game that you own (not only with rating) at least for me

Huh, you're right. I could swear I visited some game pages yesterday for games I owned where this wasn't the case... Must've been in a browser session where I wasn't logged in, then.

So, that upgrades this from a minor to a large-ish annoyance. I guess I'll write some user CSS to hide that box permanently, since I doubt I'll ever care to write a review.

Gotta agree. Let people review whatever.

and all old reviews have been removed..

I’ll have to write again why I put cyberpunk two stars out of five

When I think about buying a bundle on GOG, I want to know about the value of the bundle, not of the individual pieces of it. For that, I can only rely on reviews of the whole bundle, not on reviews of the individual games and expansions included in said bundle.

I completely deleted (not just edited) a review of mine, and wrote a new one (after having replayed that game recently), but found out that the upvotes and downvotes of the previous review remained to the new review! Wouldn't make more sense that when one posts a new review (after completely deleting his/her previous one), that the votes are cleared too? Because we're talking about a new review, while the votes are for the previous one.

I don't understand why anyone would bother writing a review for a game they haven't played but instead have watched someone else play. Isn't the whole point of a review to leave a helpful and informed opinion to others who could benefit from it? Leaving aside the outliers, I get the feeling that this sort of practice has a greater chance of stemming from clickbait and manufactured outrage, than an honest willingness to provide any sort of valuable information to others (as unfounded as it may be).

Anyway, in my humble opinion having the 'verified owners' option selected by default is a good solution to allowing non-owners to write reviews too.

About time. Editing is a prerequisite for bothering to write a review, since it's impossible to remember every little thing the first time. I can't own a review that I can't edit.

As for verified owners, it seems a bit harsh to start a store for "good old games" and then promptly expect no one to have bought and played these old games already. GOG is past that stage obviously, but still, it's their roots and they still have the good-old initiative. Better to filter out the bad ones. A lot of reviews are one-liner crap that's so utterly subjective that it means nothing to anyone but the reviewer: "I remember playing this when my dog was ill, great distraction". Yeah, no thanks. Hide that garbage.
