Well, UVL decided to cut
Gabriel Knight 3's German name in half, so I left it out of the list of alt names. Might there be a chance that the length of alt names list be expanded? Not really critical, but required to list all known titles of a game.
(The missing title for that game is "Gabriel Knight 3: Blut der Heiligen, Blut der Verdammten" but it cut it to be only "Gabriel Knight 3: Blut de")
The info page with so many different alt names looks strange. Since its only the subtitle of the games name and the main term "Gabriel Knight 3" seems to be in all the different language versions, I think everybody should find this game without problems. Perhaps leaving out the most obscure subtitles could be the answer.
Unless in case someone can't remember the name of the game series and only the latter part of the name. Much like people talk of Oblivion and Morrowind, it'd be near impossible to find it if you only had the first part of the name there ("The Elder Scrolls chapter #"). And having only the latter part of the name in alt names is Not Right, IMO.
