A 3d Diablo style grinder with no ambition, uninspired spells, and no creativity put into the story.
Anyways, this is basically Diablo 2, but in the roman times. The story is almost nonexistant. You follow a linear path and hack and slash at boss enemies. There does not seem to be that dire a purpose to all this. Something about killing a Titan god or something. It's all lost in boring npc convos.
There does not seem to be any recurring npc characters, and you are never drawn into the world of Titan Quest. It's just a long monotonous game, that is long for no apparent reason.
I quit after 16 hours, but I should have quit after 16 minutes. Don't waste your time on this one, unless you go for games that match this description.
