Honestly, this is the worst RPG I have ever played. I checked the Wiki and managed to get about halfway through the game and about 1/3 done with all side-quests. I've simply given up on this game; I was going to try to 100% it, but I simply can't. It's too bad.
For starters, the writing is incredibly bad. Rush Sykes is, by far, not only the most one-dimensional main character but also is by far the most annoying in any video game I've ever played. His only motivation is his sister; of course, it's charismatic and very noble that he wants to go so far to save his sister, but that's it. No other interests, nothing in his life. Hell, none of the other characters really have anything going on in their lives either. It's all "for Athlum" this or "for Rush's sister Irina" that. All the characters are incredibly flat and unbelievable; usually I'm able to find a character I love, but I simply couldn't here. I cared for absolutely nobody during my time playing. They all seemed to be pawn's for my battles, and that was it. Nothing more.
You have no control over any of the characters during combat - you can specify what sort of action you want them to take (heal, spells, skills, etc), but ultimately you aren't able to change the order these things happen in. This is very frustrating - for instance, I know one of my characters has an attack that can silence enemies, but I can't have him actually use that spell. It's randomized whether he'll use it or not. It's seriously moments like these that lead me to, not only dying, but getting game over over and over again. The game is punishing me for not being able to control my damn characters. You also can't customize their equipment; you're completely limited to changing the main character's equipment throughout.
To be honest, the world was fascinating at first. I enjoyed how this world did not have the standard human/elf/dwarf paradigm that many RPGs seem to have nowadays. The races constructed here are very unique and unlike anything I'd ever seen in an RPG before. It was truly a nice breath of fresh air. However, I realized that this world feels practically dead. The only real life that seems to be going on is the beasts prowling around the linearly frustrating dungeons or the vastly open, yet still dead, landscapes. NPCs in cities seem to just stand there and really don't offer anything intelligent, or exciting, to say. All the cities in the game really don't have anything going on - they're simply there for getting side quests and for buying new equipment, but really nothing is going on. It all just really felt dead, like they were simply there, which is disappointing. The point of an RPG is to escape into some sort of fantasy world (and typically to save it), but what's the point of trying to escape into a world that doesn't even remotely feel real?
All in all, I can't recommend this game. I bought it during the Steam Sale (I believe for less than $5) and didn't believe it was worth it for me. If you want a game that gives you no control over it's characters, is cumbersome, very bland, and has a good amount of content (but is only available at a limited time - after the halfway point a lot of the quests close), then this game may be for you. It, unfortunately, wasn't for me.
