I have made some test for Shining Blade difficulty and if there is a hard difficulty patch, I'll think the ajustement needed would be:
enemies HP x 4
no bonus XP at the end of the fight (only the XP earned during the fight), it's far enough and will reduce the fastlevelling and would make the game harder with no need to more ajustement.
And for someone like me who love the Shining force game as much as the new shining game, it would be more similar to how XP is gained in Shining force.
and if it's possible: 5 action point for the enemies, like the players.
And for the name of the project of, my suggestion are:
"Shining Blade: Force Edition" or
"Shining Blade: Shining Force project"
It's would be a cool way to honor the series as Shining Blade was made as an anniversary project for the 20 years of Shining Force and the Ten year of the reboot and was named "Shining Fourth: End Earth" at the beginning of the devellopment of the game (Fourth being here because it's how japanese people says "Force" and it's also a nod to Shining Force 4)
