"While "art games" and the idea that games have artistic value have become more popular in recent years, it isn't a new concept. For as long as video games have existed, there have been outliers and oddities that aimed to be artistic, literary, political, or just outside of the usual expectations of what games are. Some are good, some are bad, all are interesting artifacts of the medium's history. The list specifically uses 2010 as a cut-off date, as by that point the concept of "art games" was well established."
Original list includes notes on certain games and a link to a playlist with more information on select titles.
