ANNOUNCEMENT:
Version 6.0.3 has been released with the following features:

* Tweaked the filtering and sorting by release date and addition date to better handle unknown dates of upcoming games

I actually had issues with sorting just yesterday. Nice to see that tweak!

Glad to help. Let me know if something still isn't right.

I can't remember how many filters I used but I think MaGog kept showing games with an unknown release date despite at least filtering with addition date "is no earlier than..." and "is no later than...". Looks like it's fixed now.

Hey mrkgnao, awesome work as usual. I'm thinking of updating my drivers for some of the newer games, but this would render some of my older games unplayable, so I would like to finish them before I update my drivers. Is there any way to use MaGog to check for games with a driver incompatibility notice (like Darkstone and Rollercoaster Tycoon 2)? Thanks in advance for your time and keep up the good work.

Not a foolproof solution, for you never know where and how GOG would note this kind of information, but the best one can do under the circumstances is to search for the word "drivers" under the "Sys Reqs (Note)". MaGog finds 11 games that mention this word (including Darkstone and RCT1 (not RCT2)):

Of these, all but one (Escapists) seem relevant to your query.

P.S. Searching for the word "older" is also a good option, resulting in the same list (minus Escapists).

Whoops, my mistake. It was indeed the first Rollercoaster Tycoon.

Thanks for the list! Fortunately, it doesn't seem to be too many.

ANNOUNCEMENT:
Version 6.0.4 has been released with the following features:

* Moved MaGog's update run times forward by 45 minutes (from around 00:15/06:15/12:15/18:15 GMT to around 01:00/07:00/13:00/19:00 GMT), as GOG seems to be doing things a bit later than before of late

ANNOUNCEMENT:
Version 6.0.5 has been released with the following features:

* Improved the categorisation of patches by operating system for games I do not own

ANNOUNCEMENT:
Version 6.0.6 has been released with the following features:

* Changed table IX on the metrics page to have three age strata (old, middling, and new) rather than two

Thanks again for your constant efforts and updates!

ANNOUNCEMENT:
Version 6.0.7 has been released with the following features:

* Added "Mac OS X 10.10.0 or newer" to the list of searchable operating systems

ANNOUNCEMENT:
Version 6.0.8 has been released with the following features:

* Fixed an obscure bug that could have caused "My Notes" data not to display for games that had their game ID change in the last couple of months
*** Note: The bug affected only "My Notes" data, not any of the other user fields ("My Tags", "My Stars", etc.) and was only a display issue (i.e. no data lost)
*** Note: The only games that could have been affected by this are Trine 3, Guild of Dungeoneering, Kyn, and most of the Removed Games, and only if you had "My Notes" data for them
*** Note: Sorry for the inconvenience, if any

So that's why I can't stop coughing and sneezing.
