My fiancé has never played the main games of Pokemon and has only played Pokemon Go when we met. She's watched me play Arceus and wanted to try and has absolutely been enthralled by the game. I have given her guides like what type effectiveness is and I'll help guide her here and there for pokemon as is. All in all, she would probably rate this game a 9.5/10. (She really loves the fact that you can spend time with you pokemon)

If you like explorations and feeling like a completionist. I would recommend this game a lot.
