This may be the best entry in Sci;Adv series (科学アドベンチャーシリーズ). But I highly recommend reading Chaos;Head Noah first. There are a lot of references to previous title. Even if you decide to skip the first game, you'll enjoy one of the best time travel story to date. Steins;Gate is still my guilty pleasure. So, I hope you enjoy this game, as I did.
このゲームは悪いとわかってはいるけどやめられない。
Read the VN first, then watch anime!
