I have thought about the first one (forum) quite a while ago and even thought of a name for such a tool (DeMagog), but I'm afraid there's a technical issue. GOG limits the number of accesses a user can make to some regions of the website, locking the user's IP for 18 hours if that unpublished limit is reached. The regions triggering such a lock are one's library and the forums. Even nowadays MaGog occasionally triggers the lock. So I'm afraid even the small daily amount you're suggesting is likely to push MaGog well beyond the limit.

I don't think that accessing reviews suffers from the same limitation (at least I hope not, never tried), but I'm not sure I can see the great need for such a tool, which will be quite separate from MaGog, as it will probably be indexed by users, not by games. Nevertheless, I'll add it to my todo list (or actually my tothink list), although at the moment I won't give it a high priority.

If you can come up with useful scenarios, I'd appreciate some examples.

As witty as it is, I'm not sure I could rely on returned queries of thusly named search engine.

Have you tried to establish which frequency of requests triggers the alarm?

Anyway, I have two possible solutions. One, ask GOG technical staff to show some leniency toward your server(s). After all, you're their extended arm working in GOG's as well as its users' best interest. The other - proxy shuffling :)

If you're thinking about review indexing, usefulness of it could mainly be described like this.While reading game reviews you may encounter some by members whose writing style, objectivness etc. you find appealing, so you would naturally like to know what they have to say in regards to other games, yet you would have real trouble finding that out with the current system in place. Of lesser importance, but users might also want to browse through their own reviews, some of which they may have forgotten about since there is no list of those at the moment.

Come to think of it, same could be applied to GOGmixes with non-existent search function for those. If I remember correctly, people have also complained about not being able to find mixes they've made before. In this case, searching the title and additionaly contents would prove very useful.

I tend to believe the limit is not a fixed value, but rather dependent on server load (since it triggers more during sales and Witcher releases). Anyhow, I'd estimate it at about 2,000 accesses per hour.

I have asked GOG several times and others have asked on my behalf as well. GOG has no such plans at the moment.

Good examples. Moved it from the tothink list to the todo list, but don't expect it anytime soon, for it is after all an entirely new tool and would require much work to set up (UI-wise).

Aside from populating database initially, this should be more than enough, even if spread across the whole day, let alone an hour. My estimate is that (in GD at least, game-specific subforums are mostly negligible) there are no more than a few tenths of messages per hour.

No expectancy at all. Thank you for even considering it!

What you may not realise is that I am already doing a couple of thousands of accesses an hour for the current MaGog stuff (file changes etc.) and I constantly have to find inventive ways of avoiding the IP block as it is.

True, didn't know it was that much or that often. Plus there's The Directory of Public Wishlists *end of paid advertisement*

That actually raises a good question.
Maybe mrkgnao can name some old games that got an update many years after release, that are not related with tweaks to play better on newer versions of the OS.

For example, I heard that Starcraft still received updates from Blizzard, 10+ years after being released.
Can we see an example of this dedication on GOG?

To answer this question one has to take into account the nature of the update (i.e. not a compatibility update), which means that one needs to have a changelog (or forum post) describing the change. MaGog doesn't track forum posts, so I can't say anything about those, but a changelog is still the exception for the vast majority of GOG updates over the years, so there's really little information to work with.

Nevertheless, did a quick check and found a 2015 update for "Heretic Kingdoms: The Inquisition" (2004), which includes "Resolved one crash",

Also, there's Outcast 1.1, which is a kind of re-release (similar to the slew of enhanced/HD editions), so I'm not sure how you would consider it.

Thank you for taking the time to satisfy my curiosity. I thought that most compatibility-related updates would follow a new Windows release. But maybe they do not come out all at the same time. And I keep forgetting that MaGog is just working for a year.
Looking at changelogs would need to be a manual labour. No need for that.
Still, that is good tech support!

Very useful, thanks. Excuse me, but why it does not show "Shadows: Heretic Kingdoms"? I tried several times, but It was unsuccessful.

I only select scope => regular games. Should I check DLCs to show it?

You need "DLC" and "Season Passes" in this case. I don't know if the game should be "Regular" instead.
Anyway, to avoid this problem, I usually leave all the scopes enabled for simple title searches.

Shadows Heretic Kingdoms is not a regular game, it's a season pass.

Like phaolo said, it's usually best to leave all scopes checked, unless you're performing some special search.

Thanks phaolo and mrkgnao. :)
