- Executive Meddling:
- According to a former Iron Lore Entertainment employee, THQ wanted the game to be as family-friendly as possible: no blood, no gore, no human corpses, no demons and so forth. The Spirit mastery was subject to many changes because it was deemed "too evil". All monsters were forbidden to speak human language and display any form of intelligence. Lore Entertainment was given a bit more slack in the expansion since the game took place in Hades.
- The Ragnarök expansion features fully-human enemies. This change in game design can be attributed to two reasons: The people who grew up with the game are now ten years older, and the game has changed hands from THQ to their spiritual successors THQ Nordic and Pisces Entertainment, who made the expansion as a labor of love and in the best interest of the game's fans.
- Role Reprise: Eleven years later, Steve Blum reprises his role as Leonidas in the Ragnarök expansion.
- Screwed by the Lawyers: While the game has been released on Steam and GOG.com, the game's original soundtrack is nowhere to be found. On the other hand, the Ragnarök soundtrack is available for free, and anyone can extract the music from the game files by searching various game forums.
- Still Born Franchise: Titan Quest was supposed to have a sequel, but THQ wasn't interested in publishing it.
- What Could Have Been:
- There was originally plans to make the skills masteries reflect the Olympian Gods's powers and attributes. This is vaguely similar to Loki's faith system, another action RPG. For religious concerns, THQ forced Iron Lore Entertainment to change this so it would not offend Moral Guardians.
- Word of God said he wanted an online service similar to Battle.net so players could connect and play online together. However, THQ wasn't interested in it.
- In Act 1, there was sidequest that would have taken the player to the top of a snowy mountain. One THQ executive complained that players wouldn't understand why there's snow in Greece (Any players could have easily hop in The Other Wiki and discovered that, there is in fact, mountains and snow in Greece.) This was changed into a simple Fetch Quest in a cave for a merchant's lost dowry.
- Titan Quest 2 was going to deal with other titans threatening humanity.
- THQ Nordic initially approached Crate Entertainment to work on Anniversary Edition, since many used to work at Iron Lore Entertainment. Crate declined due to their full time commitment to Grim Dawn, another Action RPG that uses the same engine.
