Japanese Hector Hard Mode in Fire Emblem 7 was ridiculous. Kind of curious on how I'd fare if I tried it now since I'm way better at the game, but luna druids with capped magic pretty much force you to play completely differently.
FE6 normal mode was pretty difficult, so I can only assume that hard mode is even worse, but I can't get myself to try it because of really bad level design in some cases. Most of the difficulty in that game came from enemy reinforcements popping out on the enemy turn without you being ready for it, which pretty much never happens in any of the newer games. It makes for some cheap laughs because sometimes the units are particularly strong and you don't stand a chance (Rutger).
