To be fair, I haven't been playing a lot of the story. This did take a lot of time though.
The story seems to be OK, but filled with a bit too many stock plot "twists" to be really interesting. For a cheapish game, I can live with it. Dialogs are simple and rather... dull. You are presented with a block of text, follwed by another block of text and so on. Once the talking is done, you're presented with a few options (which you can repeat untill you hit the magic "stop talking" button). So far, I've found very few real dialog options.
Dialog does affect relationships from time to time, but just like too many other "RPGs" you often have no idea what the effects will be; when allowing my party to drink while gathering information, my relations with the super soldier party's alcohols is reduced.
The combat is typical for it's genre -- your party goes in order and get a few options to attack the enemy. The enemy then goes in order in the same style, untill either side is defeated. XP appears to rewarded on a kill basis -- when a party member finishes an enemy that person gets all the XP from the enemy.
Combat difficulty appears to scale much faster than your characters do. So far, I've gotten 1 level on my main character (by manageing damage so he could get more kills). In the meantime the enemies have gone from doing about 5 damage per attack to about 20 damage per attack and hit points have gone from 40ish to 300ish.
If you want to have level your main character fast, go for scout -- accuracy is the most important thing when dealing damage and scouts, at equal skill level, will be significantly better at hitting enemies, while doing roughly equal damage (that is, more damage) than soldiers or guardians.
On top of the poor combat and the bad writing, the game's performance is appauling. On a 2.8 GHz CPU the UI is sluggish, animations choppy and picking dialog options have delays. Combat is equally slow. The only part of the game which does not have extremly bad perfomance is text rendering, which is a big help, since you'll be skipping most of it anyway.
Overall, I cannot recommend this game. The balance of the game is really poor and the story simply doesn't make up for the rubbish combat.
