An excellent addition to an already excellent game!
Immortal Throne is an expansion pack for Titan Quest. It adds a whole new Act, monsters, loot, a new equipement field, formulae which gives you the ability to create special items, a caravan system, ability to share loot between your characters, a whole new mastery (Dream) and a lot more. What's cool is that all this new stuff is accessible to the main Titan Quest campaign..which makes the original game a lot better than it was.
The Good :
The excellent graphic engine looks even better, loads of new stuff to acquire and kill, the new act is fairly long and entertaining. The new Dream mastery owns! Lots of people playing it online. Gives you a good challenge.
The Bad :
You must complete the main game before having access to the new Act. The voice overs are well done but the dialogue drags on. The game gets framerate hiccups even if your PC is a beast. Highly addictive.
Verdict :
Get this game if you enjoyed TQ. If you haven't played TQ... get it with the expansion pack, makes the main game a whole better (minus the framerate thing.. it seems to affect some people more than others tho).
