Have you been holding off on purchasing R-TYPE for the Sega Master System Virtual Console on the Wii? SEGA has announced that the port of the game will be pulled from the service on September 30th. The comments section of the post indicates that it's a worldwide removal, and appears to be a rights issue.
Released on November 2nd, 2009, this is not the only game in the franchise available on the service. Super Nintendo's R-TYPE III and Super R-TYPE, alongside the TurboGrafx-16 port of R-TYPE. No word on if these titles will be pulled as well.
