And it installs the Minimalist Project, which I think it has good and bad things. It changes the play-styles and game-play difficulty drastically, but although they say it is to be more like T1 and 2, it is its own thing, which I hate. But also changes the HUD and menu to something very much like the ones in T1/G/2, which is what I love. And it also takes away 3rd person view.
I installed the Minimalist project but recovered from the backups the files that changes game-play/difficulty/play-stiles to the way it is originally in Thief 3. The sneaky upgrade is fully customizable, but I they don't offer to install the minimalist project in a modular way, so you have to manually change everything.
I've just installed the latest version of Sneaky (1.1.7.1) and it offers a pretty comprehensive set of options in a GUI - including difficulty. Maybe update and see how that goes?
The problem with Minimalist project is that it changes difficulties (easy, normal, hard and expert) to playstyles (thief, cut-purse, assassin, ghost). So, you're forced to do what you're supposed to do in those playstyles, and there's no playstyle that matches Expert in the original thief. Lowering difficulties in the Sneaky upgrade UI just changes AI sensitivity for all different playstyles.
So, if you choose ghost, you can't be detected and you can't blackjack anyone. If you choose thief, you have to collect all the loot. In assassin, there's no restriction against killing, so you're free. There's no playstyle that matches mine: The hardest difficulty and I can knock out AI, but not kill them. Also, difficult sensitivities go high up so AI can detect the smallest movement, the faintest sound, it's kind of frustrating. The changes force you to keep in that playstyle, taking away your freedom of changing it mid-mission. And the gui is amazing, but the minimalist part only has options to activate and deactivate. Minimalist changes core gameplay elements, that may newcomers and veterans off. It changes the economy, but you can play T3 without wasting a single dime in items, except those quest/plot related. So I find those changes unecessary.
But the UI is worth.
1 - The files to bring back the difficult back to normal are:
Screens.sch
UI.sch
These above change the written names of difficulties in the pre-load/debriefing screen
Take the original ones found in "..\Thief - Deadly Shadows\CONTENT\T3\Books\English\String_Tags" and put it in "..\Thief - Deadly Shadows\Installed Mods\Minimalist Project\Content\T3\Books\English\String_Tags" and overwrite the ones there.
T3gamesys.t3u
This one restore gameplay changes minimalist does to their default thief 3 state.
take the original file found in "..\Thief - Deadly Shadows\System" and put in "..\Thief - Deadly Shadows\Installed Mods\Minimalist Project\System" and overwrite.
2 - Now on the folder:
"..\Thief - Deadly Shadows\Installed Mods\Minimalist Project\System"
find default.ini, and in the difficulty tab, change the settings to the original:
[Difficulty]
; -- THIEF 3
;
; AI visual acuity multiplier - how well AIs can see
Difficulty_AIVisual_Mult_Easy=0.9
Difficulty_AIVisual_Mult_Normal=1.0
Difficulty_AIVisual_Mult_Hard=1.15
Difficulty_AIVisual_Mult_Expert=1.2
;
; AI auditory acuity multiplier - how well AIs can hear
Difficulty_AIAudio_Mult_Easy=0.8
Difficulty_AIAudio_Mult_Normal=1.0
Difficulty_AIAudio_Mult_Hard=1.03
Difficulty_AIAudio_Mult_Expert=1.13
;
; AI tactile acuity multiplier - how well AIs can feel
Difficulty_AITactile_Mult_Easy=1.0
Difficulty_AITactile_Mult_Normal=1.0
Difficulty_AITactile_Mult_Hard=1.0
Difficulty_AITactile_Mult_Expert=1.0
;
; AI hitpoints multiplier - all AI starting hitpoints will be scaled by this
Difficulty_AIHitPoints_Mult_Easy=0.75
Difficulty_AIHitPoints_Mult_Normal=1.0
Difficulty_AIHitPoints_Mult_Hard=1.2
Difficulty_AIHitPoints_Mult_Expert=1.3
;
; AI combat speed multiplier - all AI combat animations are scaled by this
Difficulty_AICombatSpeed_Mult_Easy=1.0
Difficulty_AICombatSpeed_Mult_Normal=1.0
Difficulty_AICombatSpeed_Mult_Hard=1.1
Difficulty_AICombatSpeed_Mult_Expert=1.2
;
; AI-to-player damage multiplier - all damage applied to the player by the AI is scaled by this
Difficulty_AIToPlayerDamage_Mult_Easy=0.5
Difficulty_AIToPlayerDamage_Mult_Normal=1.0
Difficulty_AIToPlayerDamage_Mult_Hard=1.25
Difficulty_AIToPlayerDamage_Mult_Expert=1.5
In Minimalist, all different playstyles have the same ultra hard difficulty settings. this changes them to the default behavior for each one. Also, play on expert. It feels more like original thief than the minimalist mod.
3 - Finally, in the folder:
"..\Thief - Deadly Shadows\Installed Mods\Collective Texture Pack\Textures\Content\T3\PCTextures\DynamicallyLoaded"
rename or delete the files gentrainingfeet.dds and pointyb01.dds. These are textures for the foot-prints and pointy arrows in the tutorial level.
It's a little work, but this will bring the default gameplay and difficulties from thief 3, but keeping the UI from minimalist mode.
Actually, you just need to restore the "T3gamesys.t3u" in minimalist project folder and the restore the original difficulty tab in the default.ini in the minimalist folder. The game will play normally as intended, only the menus will show the wrong names in the difficulty tabs.
I highly recommend making these changes if it's going to be a 1st playthrough.
