Released for the Nintendo Entertainment System in 1988, Ys I is a role-playing game developed by Victor Entertainment and published by Nihon Falcom. This NES release is a port or adaptation of a game that first appeared in 1987.

It landed about 3 years into the NES's life. Other notable NES releases from 1988 include Super Mario Bros. 3, Super Mario Bros. 2 and Final Fantasy II.

It is part of the Ys series; on the NES you can also try Ys II and Ys III: Wanderers from Ys. The series also appears on other systems with Ys I (Master System) and Ys IV: Mask of the Sun (SNES).

Ys I is a single-player game, so it's one to enjoy at your own pace.

Pick it if…

  • you want to get lost in a long quest
  • you have time for an epic journey (20+ hours of adventure)
  • you've played the NES hits and want something less obvious

Maybe skip it if…

  • you want instant action rather than menus, story and grinding
  • you are looking for something to play with friends
  • you only have a few minutes at a time

What playing Ys I is like

Role-playing games trade reflexes for strategy and story. You build a party, level up, manage equipment and travel across a large world, usually through menu-based battles.

Tip for newcomers: Retro RPGs can require some level grinding and rarely tell you exactly where to go next. Talk to every townsperson, save often and use a guide if you get stuck: there is no shame in it.
