SEGA has quietly confirmed that it will be ending the online services for Rhythm Thief & the Paris Caper at 6 PM (UTC) on September 28th 2015. This game isn’t the 3DS version, its the iOS adaptation released under SEGA Networks back in 2013. The iOS page for the game has the following message:
“The game went live on October 28th in 2013, and we have constantly strived to deliver a fun and engaging experience. This decision came as a result of various circumstances beyond our control. Again, we would like to thank you for playing. July 28, 2015 – Last day of in-app purchase sales, September 30, 2016 – Last day of service”
Like most SEGA Network games, Rhythm Thief & the Paris Caper has always-on connectivity requirments without the ability to play offline. I would say that SEGA shutting down the online services basically means that this game is now unplayable… unless SEGA patches it to work offline.
