Mildly amusing for half a second, good for achievements/trophies, and won't break your wallet.

But you just click a jar.

YOU JUST CLICK A JAR.

A LOT.

MY FINGER HURTS AND MY HEAD IS BORED.

Some incredibly strong story chapters that really appeal to what makes Fate work. At its best, the main story chapters feature engaging and powerful character writing set across great thematic and physical landscapes. The best of these chapters have an intense sense of rising action as ya ride towards the climax. These are what you play FGO for and why the early story chapters are worth getting through.

At the same time, has a bunch of incredibly whatever event stories that don't usually amount to much more than assorted characters showing up for jokes and light storytelling that doesn't go nearly hard enough to land. Even if they're occasionally fun little breathers, they ultimately end up feeling like wastes of time that don't really compare favorably to Fate's other lighter experiences. I largely just ignore most of them nowadays, save the rare event that has more to it. And I'll largely argue that most of the Gudaguda events are actually a pretty fun mix of goofy and serious content.

Oh, and there's gameplay too, I guess. It's fine. Sprites look better than most other mobile games. I like when story bits influence the battles. Actual battle system isn't bad. That's about it.
