Obviously, because of the nature of my YouTube channel, release dates of old video games are of particular interest to me. A few years ago I got some help from a few folks here in trying to piece together the likely launch lineup for the TurboGrafx-16, but since then I have found a great resource for release information from back then, in the "Computer Entertainer" newsletter. Every month they had a list of games for each system, which included both the expected release month of games not out yet, and more importantly marked games that had shipped out to stores since the last newsletter. So say in October you might see "Blazing Lazers" listed as expected to release, and then the following month it would be marked as having already shipped. So you can more or less narrow things down to the month that they came out. So with that in mind, here is a list of the TurboGrafx-16's releases for 1989.
