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.
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.
