Mythological RPGs are surprisingly rare, but Titan Quest does its best to make up for it. As a Greek hero trying to find the source of a monster infestation, you'll travel across Greece, Egypt, the Silk Road and China, then climb Olympus, descend into Hades and cross the Bifrost into Valhalla. No one can say this is “just another Diablo clone”.

Alongside the mythological setting, Titan Quest's defining feature is its character system. Instead of classes, the game has eight masteries (ten with the expansions), each with its own skill tree. The trick is that each character can learn up to two masteries. So you can pick the Earth mastery, which specialises in AoE spells, and play a pure caster; combine it with the Defense mastery to increase survivability; or with the Storm mastery for more single-target spells; and so on. It's a fascinating and deep system that allows for 55 different mastery combinations, plus the variations from your choices inside each individual skill tree.

Each mastery was supposed to be tied to a god, but higher ups asked the developers to avoid controversial and religious themes, leading to a mythological game that doesn't really explore its setting. This, the low game difficulty and the simplistic loot system can make the game feel underwhelming at times. On the other hand, the 6-player co-op definetly makes it stand out.

Another great feature are the visually stunning landmarks, like Athens, the Great Wall of China or the Pyramid of Giza. However, unlike other Diablo-like games, the world of TQ is static – enemies and areas are always the same, greatly reducing its replay value.

This is made worse by the game's difficulty system, where you must complete it twice to unlock the highest difficulty setting (which has additional bosses and items). This was how Diablo II worked, but Titan Quest is a longer game and doesn't have the same replayability.
