Thief Gold ratings:
1. Song of the Caverns — I consider that one to be the best level in the entire series. Starts off as a cave exploring endeavor but soon transforms into infiltrating a huge opera house chock full of guards and valuables to pilfer. While not the prettiest level by any stretch (some parts look downright ugly), it is the one I have the most fun with. The sound design is impeccable, the exposition pretty much perfect and the layout itself is excellent. This and
First City Bank & Trust are my favorite manor-type original missions by far.
2. Break From Cragscleft Prison —
Winterlight articulates my thoughts better than I do. It is the level that truly hooked me. It is a terrifying experience with an absolutely crushing ambiance, and the difficulty is very steep compared to the previous level.
3. The Sword — Masterful level design, with some of the most memorable moments in the series (the famous twisted corridor is imprinted in every taffer's mind, and that giggling in the upper levels drives everyone mad). Maps like the Clockwork Mansion in Dishonored 2 owe a lot to this level.
4. The Haunted Cathedral — The open-ended, interconnected layout makes this one an absolute joy to explore. You have a city block all for yourself with only a few Undead and other critters to take care of. The mission has a really powerful aura of mystery surrounding it and when you finally see the Cathedral and its ominous presence you know something really nasty happened here.
5. Assassins — Despite being very easy, it is still one of my favorite levels. The twisted, dark streets of The City are just so incredibly immersive and real, and tailing the two shady assassins who think they killed you so you can rob their master is a truly awesome premise. This mission really shows that Garrett is definitely not one to be trifled with. The guy can get anywhere, and by swiping Ramirez' purse he's telling him he could have killed him with nobody ever catching sight of him.
6. Return to the Cathedral — The scariest mission in the series. The fetch quests can be a little irksome after a while, but the atmosphere is so incredible and the level so challenging I overlook this.
7. Down In the Bonehoard — One of the best dungeon crawling experiences I've ever had, which really showed me that Thief: The Dark Project was much more than 'merely' a great stealth game. The Horn of Quintus soothing the Burricks and lulling them to sleep was also a very nice touch. The original texturing in TDP is much better than TG's.
8. Lord Bafford's Manor — A very easy and basic level but the atmosphere of anguish is unmatched. This level freaking terrified me when I first played it; the sound cues, the ambiance, the surprisingly clever AI, etc. Such a great introduction to the game, perhaps one of the best first levels in any game I've played.
9. The Lost City — Really fun tomb-raiding level with a super confusing layout at first, though now I know it by heart and never get lost anymore. I really love the map, that looks like a giant middle finger at first but is actually rather easy to read after you're familiar with the locales. TDP's version is much more interesting than TG's though.
10. Escape! — Not the most interesting level by any stretch, but I really like how brutal it is. This one will really test your skills and patience, and makes a lot of sense story-wise and for Garrett's character development.
11. Into the Maw of Chaos — Incredibly fun and trippy, but also incredibly linear and easy.
12. Thieves' Guild — I love how challenging it is. It's not that difficult to navigate in though, if you carefully listen to people and read notes. The map is also surprisingly detailed. That said it's not very memorable and doesn't look particularly good. It clearly doesn't deserve all the hate it gets though.
13. Undercover — Not a huge fan of Undercover. I love the Hammerites but the level is too small, too easy and social stealth doesn't work all that well in Thief.
14. The Mage Towers — Downright ugly and gets old pretty fast. Some bits are cool, like the central keep, and I love the mages. The audio in this level is also top notch.
15. Strange Bedfellows — Pretty dull and far too easy. Me not liking Undercover much is also a con for this level.
Thief 2 ratings:
1. Life of the Party — Everything in this level is perfect. The most interesting, freeform layout out of any mission in the entire series. Life of the Party is a herculean endeavor and mercilessly stomps the crushing majority of levels that came after it with its sheer size, incredible scope and downright brilliant execution. It is so good in fact that all the following levels, with some being very very good, still pale in comparison. The demo version is
slightly better than the final version though.
2. First City Bank & Trust — Huge, full of guards, lots of security devices (semi-randomized on Expert), lots of loot, very interconnected layout with lots of entrances. This and
Life of the Party is what being a master thief is all about.
3. Masks — The vastly superior hot sister to
Casing the Joint. Rather challenging and just a joy to sneak through. The audio, much like
Casing, lulls you and the rain outside makes the place feel very warm in comparison. This one is so much better than
Casing the Joint you just wonder why they included it in the first place (yes, I know why).
4. Sabotage at Soulforge — Love how incredibly tough and HUGE this mission is. I don't really understand people who call it tedious, to me it is an incredibly fun level with many challenges. Hearing Karras slowly lose his cool when you run through his death machine conveys a lot of tension.
5. Trail of Blood — The closest there is to TDP/Gold in Thief 2. It's a very fun level, though very linear in the end. Pretty melancholic too.
6. Blackmail — This level excels at tension. The red corridor before you learn Truart's been murdered is extremely memorable. The mansion is a bit too small though.
7. Running Interference — A good introductory level, though much inferior to
Lord Bafford's Manor. I really like the feeling of dread and uneasiness that oozes from it, though, as the manor appears to be a holiday estate and is completely empty save for a servant and the guards who are here only to keep Jenivere from getting away. It's a very romantic story (not in the sense of a love story).
8. Shipping... And Receiving — A bit dull after a while, the layout is great but the level itself doesn't interest me very much. The swelling horn is a great musical piece though and gets stuck in your head.
9. Framed — Love the audio design in that one as well, but it ultimately lacks spice.
10. Eavesdropping — Really good concept and nice real introduction to the Mechanists, but the level is too small and far too easy!
11. Precious Cargo — Not a huge fan of this level. It's average, nothing special. The bit with Lotus is touching and the Cetus Amicus is interesting, but eh.
12. Ambush! — Iikka Keranen designed this level but even with his magic it's pretty dull compared to the awesome dark and twisty cityscape in
Assassins. Everything is kind of samey and not very interesting-looking. The level is also incredibly basic and becomes dull after a while.
13. Casing the Joint — The boring sister to
Masks. The level is empty as fuck with nothing to steal except coins. Great audio though, but
Masks is just so much better in every aspect. Incredibly unnecessary level.
14. Trace the Courier — Really boring, kind of lazy and so short you completely forget about this one after you've played it.
15. Kidnap — Just awful. This one is easily my least favorite level in the entire series (not counting Thi4f). It's just not fun. Seeing the Lost City again is great but what's the point if you turn it into a really boring trudge through areas that worked incredibly well with exploration in mind but become incredibly frustrating when populated with bots and Mechanists everywhere?
