As far as the game being a gacha goes, it has got to be the most F2P-friendly gacha I've ever gotten into, and I've been active in maybe 20+ different gachas since I started Fate:Grand Order in its second year. The grind is still a grind, but there's ways to give it a little freshness every day while waiting for weekly resets and new content.
The gameplay will be very familiar to players of Library of Ruina, it's hard to explain in words.
The story and its characters... It's so ♥♥♥♥♥♥♥ peak, man. You gotta get into this.
