Teenage Mutant Ninja Turtles: Turtles in Time Reshelled - now that's a long title! - is being delisted on PlayStation Network on June 30.
This is coming about due to the license expiring on that date. While PlayStation Network is telling people to buy it as soon as possible, Xbox Live Marketplace makes no mention of the potential delisting, though if it's a licensing issue, it'll probably be wiped from XBLM too.
The remake of the NES classic wasn't well received by critics or fans, however. The game received a 60 Metacritic when it was released two years ago.
