michal.czernow: @Petrell Could you please specify games that are filtered in bad way? Also -- do you get the same wrong results in catalog?
Using role-playing filter:
Avernum 1-6 (from Avernum: The Complete Saga)
Betrayal in Antara and Betrayal at Krondor (From Betrayal at Krondor Pack)
Geneforge 1-5 (From Geneforge Saga)
Two Worlds
Two Worlds II Velvet Edition and Two Worlds II Castle Defense (From Two Worlds 2: Epic Edition)
Depths of Peril
Drox Operative
Din's Curse
Wasteland 2 (WL1 shows, my WL2DE is Kickstarter reward version so problem must be there)
Spellforce 2: Demons Of The Past (3 other titles of the series show)
Sudeki
Risen
Risen 2: Dark Waters
...among others. I sent a longer list, including some examples of games missing from other genre filters with my support request.
Oh and do use reply feature next time so I get notified about reply to my post ;-p
Edit: It appears that problem is with limitation/implementation of GOG genre filters and apply both library and catalog. Only first genre game is set to is taken into account so Risen 1&2 (Action - Role-playing - Fantasy) will only show under action, not role-playing and The Lords of Midnight and Doomdark's Revenge (Role-playing - Strategy - Fantasy) show under role-playing but not under strategy. I hope GOG revises the filters as personally I find it confusing that I would have to look for ARPG's under action rather than role-playing or stategy game with role-playing elements under role-playing rather than stategy. Fact that games from same series may not show under same filter adds further confusion (like with Spellforce 2: Demons Of The Past above).
Avernum 1-6, Geneforge 1-5, Betrayal in Antara and Betrayal at Krondor not showing up under their primary genre filter appears to be bug caused by unbundling and problem with Wasteland 2 seems to be related to it being Kickstarter version.
