Check out IGN's review of the expansion to Titan Quest - Immortal Throne. Titan Quest did offer a rather enjoyable experience (at least while waiting for diablo 3!), with customizable classes, lots of loot options and a fascinating setting. Immortal Throne looks to add to all of that with a higher level cap and lots new areas to explore and monster to defeat.

Though we can hardly claim that Titan Quest was too short, Immortal Throne adds a rather sizeable chapter to the game. After the end of the original game, players will find the doorways to hades open to them. There are several new large areas here, each of which is full of interesting quests and terrifying monsters. While many of the areas are basically dark caves, there are some bright spots here and there, particularly in Elysium, and some truly memorable vistas.
