Holy shit, Fire Emblem Fates has now joined the 1000+ hours playtime club along with Splatoon/2! Did not realize I'd been playing it for that long, and still plenty more to go too! Currently finishing up Revelation Lunatic/Classic with no grind/dlc/online, then I will do another Conquest run with the same settings/rules, including Endgame this time. Had no choice but to break my rules on my first run through, but this time I'm fully aware of the absolute bullshit insanity that is Endgame and have devised a strategy for it. One simply can't say they've truely mastered Fire Emblem until they've legit beaten Lunatic/Classic Conquest afterall!
So yeah, it's clear this game is the peak of the Fire Emblem series for me atleast. I'm sure Three Houses will be good, but there's no way it'll be better than Fates, definitely not gonna have this as an expectation for the game. The only way to accomplish that feat would be to pretty much copy-paste Fate's gameplay (more specifically Conquest) but have an actually good story that's sold in a single normal priced package.
