TQ: Immortal Throne - Reviews @ GameSpot, GameSpy, CVG, Yahoo Games

A few of the big sites have reviewed Titan Quest: Immortal Throne, with GameSpot turning in a 7.9/10, GameSpy a 4/5, CVG a 7/10 and Yahoo! Games at 4/5.  Let's start with a clip from the first:

Immortal Throne doesn't skip a beat following your defeat of Typhon at the end of Titan Quest. As you descend from Olympus, you find that the world is still in chaos and infested by monsters. So, you continue on your quest to figure out just what in the hell is going on. Turns out, hell is exactly what's going on, as much of Immortal Throne has you hacking and slashing your way through the surprisingly diverse underworld of Hades. You might assume that spending 10 to 15 hours fighting your way through Hades would mean a nonstop barrage of dank, dark dungeons. There's definitely plenty of foreboding areas in Immortal Throne, but there's also a good variety to the environments you'll fight your way through, from the sterling white marble of Rhodes to the flowing golden fields of Elysium. The game isn't shy about appropriating bits and pieces of Greek mythology as it sees fit, pitting you against the three Stygian witches who share a single eye and the three-headed Cerberus that guards the banks of the river Styx, while also having you interact with the sorceress Medea, as well as Greek heroes like Agamemnon, Odysseus, and Achilles.

...and a bit from GameSpy:

Iron Lore did a pretty darn good job in making Dream Mastery fun to use. While most of the original Masteries are pretty focused (i.e. Defense is for tanking, Earth is for nuking), Dream Mastery goes for the "does a little bit of everything, and kicks ass" line of thought. Notable Dream skills are the psionic burn, which adds a significant damage boost to your normal attack; Trances (Titan Quest speak for the Auras from Diablo II's Paladin) that can either boost healing, inflict damage, or even convert damage into health; a slick area-effect attack called Phantom Strike, and a pretty awesome pet (the Nightmare, a floating eye that can confuse monsters and give bonuses to all of your other pets).

But at least they've given us enough new stuff to warrant another playthrough, plus the ten or so hours it'll take to go through hell. Not to mention the extra time you'll spend collecting ingredients for your artifacts. And then there's the time it'll take to level up a new character with Dream mastery. Plus the new characters you'll want to make to use the great loot you found that you can't use. Diablo 3? Never heard of it. We're too busy playing Titan Quest.
