Limited Run Games announced on Twitter that a physical Broken Age release will be available for pre-order on the 12th of October, and will only be available for two weeks. The Limited Run Switch release of Broken Age joins its PlayStation 4 and PlayStation Vita brethren, as the latter had physical versions released by Limited Run Games back in 2017.
Switch cartridge production takes a while and once the cartridges are finished, they need to be shipped from Japan to the United States, where Limited Run Games will pack the cartridge in a standard Switch case. The cool thing about these Limited Run Switch releases is that each game comes with a complete byte-sized manual, which is a really rare thing nowadays.
Because of the long production time, it's likely that the Limited Run physical release of Broken Age for Switch won't ship until January.
