This Japanese RPG was released on CD-ROM only on the PC Engine, so required a disc player to work. Ys IV: The Dawn of Ys was first released in 1993 and was developed by Hudson Soft as a single-player, cinematic, cartoon-style RPG, with real time combat and exploration.
The Dawn of Ys is the fourth game in the Ys series, although – weirdly – there are two episode fours in the Ys series, so it’s easy to get confused by the titles. The games themselves are quite different though.
