Concerning individual works
Concerning the game trilogy as a whole :
- Alternative Character Interpretation : Does Garrett keep helping others and saving the world because he's a Knight in Sour Armour, or is he just a pragmatic egoist?
- Complete Monster: Karras and Gamall
- Demonic Spiders: Haunts. Extraordinarily creepy, cannot be black-jacked, best fighters in the game, extremely fast... even players who are used to fighting their way out of a bad situation will be extra-cautious around Haunts.
- Ensemble Darkhorse:
- The two guards that keep showing up to guard different places and people throughout the games, providing a number of memorable conversations (most notably the "bear pits" conversation from the very first mission of the first game).
- The Hammer Haunts are also the most popular and fondly remembered of the undead in the series.
- Goddamned Bats:
- Spiders are annoying and the larger varieties (especially Chaos Spiders) can be pretty dangerous, but they aren't hard to kill. They are easily susceptible to a One-Hit Kill with a broadhead arrow, as long as they don't spot you (they have fairly rubbish vision, so it's really easy to kill them). A few slashes with the sword can kill them as well, but you're more vulnerable while doing so, since you have to stand close to them to deliver a blow.
- Frogbeasts have an explosive capability, and have been regarded as a common nuisance.
- Hell Is That Noise: The Thief series has been well known for occasions with a rather disturbing ambiance.
- I Am Not Shazam: Though it sounds like a nice and fairly logical alternative name for their faction, from a purely canon point of view, the Pagans are NOT known as "The Order of the Vine". That doesn't stop some fans from including such references in their fan works, including fan missions.
- Iron Woobie/Jerkass Woobie: Garrett, particularly after his chain of traumatic experiences in the final third of The Dark Project.
- Memetic Badass: Garrett. He has joined the ranks of "Impossible thieves in fiction that can rob you blind no problem."
Fan missions, mods and other fan works :
- Fan Wank: Since the storylines of many fan missions often extrapolate from established Thief canon, you're bound to bump into something based on WMG by the series' fans.
- It's Short, so It Sucks: The number one complaint about any fan-mission is "I wish it were longer!" Not to say that FMs are bad or short (many of them rival the original missions in length and complexity), but since most FMs are single-level, the fun can only last so long.
- They Changed It, Now It Sucks: Completely averted; almost any change to the status quo is seen as a brilliant innovation, especially when pulled off right.
