A little more than a linear still fallout 2 or Arcanum (particularly on the influence of dialogues on history), but very enjoyable to play. The scenario seemed full of twists, and he stands.
The characters have a real personality, the atmosphere is very fascinating, even for me who am not a fan of Star Trek universe which are yet lifelike.
I recommend it to any RPG fan who attaches much importance to characters and dialogue that the strategy of fighting.
