$45 million, the ambitious scope of Final Fantasy VII raised the possibilities for the genre, with its more expansive world to explore, much longer quest, more numerous sidequests, dozens of minigames, and much higher production values. The latter includes innovations such as the use of 3D characters on pre-rendered backgrounds, battles viewed from multiple different angles rather than a single angle, and for the first time full-motion CGI video seamlessly blended into the gameplay, effectively integrated throughout the game. Gameplay innovations included the materia system, which allowed a considerable amount of customization and flexibility through materia that can be combined in many different ways and exchanged between characters at any time, and the limit breaks, special attacks that can be performed after a character's limit meter fills up by taking hits from opponents. Final Fantasy VII continues to be listed among the best games of all time, for its highly polished gameplay, high playability, lavish production, well-developed characters, intricate storyline, and an emotionally engaging narrative that is much darker and sophisticated than most other RPGs.

The genre became with the game that set the template for tactical RPGs, Fire Emblem: Ankoku Ryū to Hikari no Tsurugi (1990). Treasure's shoot 'em up, Radiant Silvergun (1998), introduced an element of narrative to the genre. It was critically acclaimed for its refined design, though it was not released outside Japan and remains a much sought after collector's item. Its successor Ikaruga (2001) featured improved graphics and was again acclaimed as one of the best games in the genre. Both Radiant Silvergun and Ikaruga were later released on Xbox Live Arcade. The Touhou Project series spans 22 years and 27 games as of 2018 and was listed in the Guinness World Records in October 2010 for being the "most prolific fan-made shooter series".
