If you're going to provide the release dates for each game, it would be best to have the original release dates not the ones you see on Steam; also Higurashi When They Cry wasn't based by the anime, its the other way around. Here are some examples of what I mean:
Higurashi When They Cry - Onikakushi (JP: August 10, 2002 WW: December 15, 2009)Umineko When They Cry - Legend (JP: August 17, 2007, WW: July 8, 2016)Aokana - Four Rhythms Across the Blue (JP: November 28, 2014, WW: September 27, 2019)Song of Saya (JP: December 26, 2003, WW: May 5, 2013)
Raging Loop (JP: August 3, 2017, WW: December 5, 2019) the one on the list had the date for the Switch, not Steam which is August 23, 2017
