While I think it's an absolutely untraditional game that won't appeal to everyone, those who are willing to explore it and give it a chance will find one of the most mind-bending narratives in a video game...and it's kind of one of my favorite anime games out there (which frankly isn't saying much as I've only touched the Fullmetal Alchemist games on PS2 and this.)

If you liked the anime and wanted more Lain and are willing to put up with some very unconventional game design...I'd say it's worth it. You can play it for free here: https://3d.laingame.net/#/
