The game is graphically stunning and beautiful. Worth to try even as a F2P. Gameplay is a bit boring, long and feels repetitive for some and for others it's a complex turn based game that is quite fun and engaging. Furthermore, game runs heavy on Android even with low setting with 60 fps. Setting aside the gacha mechanics, the game is definitely worth playing for past times or casuals.

The game's combat system is terrific and so is the gacha. F2p players can actually pull most limited characters without issue. Also story really ramps up later on.

Generally very enjoyable game. If you want a lot of Servants though, you must have tons of money or tons of patience. The story is passable, the fighting is good, but the gacha aspect still irks me. I'm F2P but I'm still having fun. Don't let gambling discourage you too much.
