I enjoyed this more than I thought. Back in the day I really liked Septerra Core (mark my words, Nightwar is nowhere near as grindy and repetitive as SC was) and kinda dislike the JRPG style. But this one got me hooked and introduced me to a pretty cool comics series (and the frustrations it contains). Highly reccomended.
This game does turn-based combat right. Enemies are challenging and each type is designed to have its own combat trick to be more than just a bag of XP. The characters have a variety of different abilities to handle different situations and trying to output max damage from every character is a good way to get your team wiped. It's possible to tackle enemies several levels above you if you're willing to make use of the consumable tools at your disposal and build a team with different specialties. I've seen reviews saying that the game is grindy, but after setting everything to Legendary difficulty, I didn't feel like I was bored. Unfortunately the benched team members don't share combat XP, so you're less and less incentivized to experiment with new characters as the game progresses.
If you're not already familiar with the Battle Chasers story, you won't feel very attached to the characters as they're presented here. The voice acting is all very good, but the dialogue is pretty standard fair. The characters are all archetypes without much depth. Don't expect development or arcs. The ending is strangely abrupt and not very satisfying, but I enjoyed the dungeons I crawled through to get there.
The world itself is well-designed with plenty of sidequests and hidden areas in the world map. Each dungeon after the first has its own gimmick and personality with random mini quests sprinkled throughout it. The art style is colorful and fun to look at and the battle animations feel very satisfying to watch.
The crafting system is a bit odd; after running a dungeon on Legendary, I didn't feel it was necessary to spend time re-running it to get materials I needed for stuff that I felt was going to get replaced by drops in the next dungeon anyway. I only spent time on it in the end game; I do like the idea of putting in more items than you need to get an epic version of the equipment. The game also lets you stick custom enchantments on armor and weapons.
Its have been a long time since i could ever finish a game without getting bored, this game has that thing old games had and new games dont. You know what i mean.
