One game can have different names so for instance Trace Memory (2005) is also known as Another Code. This can happen when publishers choose names they think are good for their region, or with different translations. Games like Carol Reed 3: Time Stand Still (2006) might turn up as just Time Stand Still or Carol Reed 3. Games like Trüberbrook have non-ascii characters in their names which complicates matching. Human error can creep in so Silverload (1995) might appear as Silverlode.

Games can share names. So Treasure Island is the name of games from 1995 and 2008 and also 2010.
