In the video game infobox template, there are often several release dates for a game based on region and system. These end up in dbpedia as a list of dates with no other information attached.
Example - Halo 4 has two release dates, one of which is for Japan.

Example - The Witcher 2 has several release dates; none of them are actually parsed properly, and none of the related information is preserved.
