I see too many reviews for this game from people who have not given it enough gameplay time.
I can in fact say that the game lacks polishing, the story is highly forgettable, music is passable, characters have mild customization and there is no loot besides bandages, graphics are dated, pathfinding is strange, character skills and abilities upgrade oddly, etc etc.
However, in what it aims to be, which is a tactical RPG, it totally fails in the RPG part, but it's quite challenging in the tactical part: it's not a cakewalk in the "easy" setting and it's definitely complex in most encounters in the "hard" setting. In that regard, in making some micromanagement of skills, buffs, debuffs, AoE, etc, I'd say it's quite alright and even unforgiving on the player. It's not a D&D title, it's a B-series game, but if taken for what it is and graphics, story and such is put apart and the tacticality of the gameplay is highlighted, can be an interesting title to play.
When the game was over, though, I felt a bit tedious of it, I didn't even play the extra maps since I was so fed up! The campaign is way too long! I don't recommend playing it in long runs, as it can be a bit repetitive, most game is just linear walking and encountering battles.
I don't think it's worth the full price, I got it in a bundle and for that I believe it is more than acceptable.
Considering it is a mixed bag, I cannot recommend it for the average player. But if searching for a challenge, do take a look at it (in a bundle!), and for that kind of player I'll give a "yes".
