Not the worst JRPG you've played, but it's the most frustrating and annoying of them...
-Keyboard+mouse controls... looks like people who ported the game saw K+M for the first time in their lives, gamepad is strongly recommended.
-VERY limited control of your units. Every turn you have 5 random options to chose from and thats it. You might have no option to heal when you're desperately in need of it and you might be screwed even if you have it cause you can heal with ITEMS or MAGIC or both and you will get the one which isn't so powerful.
-No matter what, your weakest union WILL be gangraped 99% of the time, every monster on the field wants their blood.
-Monster AOE spells are overpowered beyond belief, even the weakest monster in the area (~same level as you) can onesot your party in 1 turn. Lets say normal monster attack hits for 100, singletarget ability hits for 300, AOE ability hits for 300 every unit in your union, which will result in 1500 damage on 5ppl... Some BIG monsters can AOE multiple unions and erase your party in a single spell... and they will cast it FREQUENTLY.
-You can't surrender, so if you're trying to beat a very strong rare enemy and it destroys half or your units on the first turn... you must watch the other half die, sometimes very slowly.
-You CAN'T skip cutscenes. After some cutscenes you will be immediately thrown into battle, and if you lose it... load your save and watch 5+ min cutscene again.
-You can equip only your main protagonist, others can only request some components and RARELY items from your inventory, so you can sit on a pile of top gear and no ability to use it. It's not a huge minus anyway, cause all you have is main/offhand weapon and 2 accessory slots.
-Though locations are pretty unique and well done you will be forced to visit them over and over again if you want to complete sidequests or hunt for rare monsters for the guild. Every quest teleports you to corresponding location and teleports back to tavern IMMEDIATELY after it's completion.
-The world and lore are really interesting, but the story feels like it's written for the 12 y/o. This "flaw" can be seen in almost every Japanese game (atleast in my experience) and can be forgiven.
-Battle system is pretty good for a JRPG, but it's very annoying that you can't skip battles with weak monsters when revisiting old locations.
I'd give it 6/10, but put a huge red FRUSTRATION WARNING on it.
