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.
