JRPG darling Chrono Trigger took its time coming to PC. 23 years, in fact. Lamentably, the version we got was a mobile port, itself based on the DS port, laden with an awful UI that was designed for touch screens, ugly “high-resolution” graphics and some extra bugs for good measure. This put something of a damper on its surprise arrival. There’s still some hope for it yet, however, as a series of updates were just announced. 

“We have been working on addressing the issues that you’ve raised, and will be releasing a number of patches over the coming months as we continue to support Chrono Trigger on Steam,” the update on the Steam page explains.
