The Granstream Saga is lauded as one of the first fully polygonal RPGs, as opposed to using polygonal characters with pre-rendered backgrounds, polygonal environments with scaling sprites, or other such combinations. The game features anime-style cutscenes by Production I.G. It is also somewhat unusual in that the characters the player meets in the game are faceless.
- Anti Anti Christ: Eon is the reincarnation of this world's Satan, the "Mah Oh", from the previous version of the world. However, being adopted by the Old Hermit, he grows up good and just and defeats the current "Mah Oh".
- Amazing Technicolor Population: Two of these. One is against the final boss, naturally, who is a sapient-can-comprehend-mortals Jerkass Eldritch Abomination, and earlier, in a Mad Scientist's castle. The battle is against his experimental world-ending giant creature, and you have to destroy its heart from inside. While you're fighting the heart blood vessels can be 'seen' transparently from above as if you're really looking down into the battlefield, and the entire room pulsates and shifts with his heartbeats. Both trippy and disorienting.
- Eldritch Abomination: The final boss, as listed under Amazing Technicolor Population.
