Current example (as of v14): # 16202 (Planeet der Gevaren) has been removed from Gamebase for a good reason, as it was a hack of an English game with just some texts changed.
The game in question is NEOCLYPS (# 5175, http://www.gb64.com/game.php?id=5175&d=18 ).
Now look what the comment text is saying:
Perfect! Now think that a Dutch user comes along, who only remembers the Dutch (fake) name.a.k.a. "Neoclips", "Planeet der Gevaren" - read Notes
By searching in Comment field, he might find a match to the actual game he could no longer remember up to now.
Side-effect:
People will no longer suggest "new games not in Gamebase" which are simply hacks, since they will now be able to search for the fake name(s) mentioned in Comments only.
