Is there a way to try to feed the items on reports of Wikidata:Database reports/Deaths at Wikipedia into http://tools.wmflabs.org/wikidata-game/#mode=no_date either directly into the game and/or a special mode?
The game currently attempts to find mainly P570 for living people ;)
BTW, the date parser might need update to the new format. If a date is already defined, it displays something like "date of birth-01T00:00:"
