It was published on GOG.com in May 2015 with support for Windows, macOS, and Linux after GOG Ltd acquired the copyright to the title.

[4] A successor called Fantasy General II: Invasion was released by publisher Slitherine Software and developer Owned by Gravity in 2019.

The soundtrack to Fantasy General was arranged by Rick Rhodes and Danny Pelfrey and featured soprano Marisa Lenhardt.

The game's music featured original settings of Strife is O'er, the Dies Irae, the Easter sequence Victimae Paschali Laudes, Let All Mortal Flesh Keep Silence, Dona Nobis Pacem and two works by Johann Sebastian Bach, Komm, süßer Tod, komm selge Ruh and Wir essen und leben.

They did, however, also criticize the instability on Windows 95, simplified magic system, and lack of scenario descriptions but overall rated the game as equal or more to its predecessor.

[15] A reviewer for Next Generation commented that typical war simulation fans would likely be turned off by the game's unhistorical setting, lighthearted atmosphere, and lack of challenge, but that its solid sense of fun would make it entertaining for those willing to try something different.

[10] Andy Butcher reviewed Fantasy General for Arcane magazine, rating it a 7 out of 10 overall.

[7] Butcher comments that "Fantasy General is good but not great - you can happily while away a few hours with it but it's unlikely to keep you up 'till three in the morning for 'one more go'".

[18] Strategy publisher Slitherine Software and developer Owned by Gravity announced a sequel Fantasy General II: Invasion for Microsoft Windows in April 2019.

[27] The New Zealand magazine NAG called the game a "worthy, lovingly crafted successor".
