Atelier games are cute RPG games separated into two parts. first, the adventure and battle RPG and second, the crafting and alchemy system. what makes this game worth playing on the PS4 is the time and weather effects. As the day goes by, your shadow will change to reflect the position of the sun and grow longer or shorter, and there are storm, wind and rain effects which the VITA version does not have as detailed. past games, the alchemy was a bit hard to learn to make advanced items. but every game release has a different alchemy system and atelier firis has the most simplified of all. that is not bad, it is still fun, just less complicated to learn to make the best equipment. the game is very long or very short, depending on what you want to do. completing the main story does not require any grinding or complicated equipment making. you can also turn on easy mode at anytime and switch between modes if you just want to gain exp or farm items. of course, the best items come from hard mode where you can choose to fight optional end game bosses that require good equipment to defeat. overall, if you are new to the series Atelier firis is the best place to start. the graphics are high quality and there are lots of neat exploration items available that are new to the series.
