Hardest difficulty completed: Hard

Marines and Zealots only
It is not allowed to make scvs or get mercs. You can use non-marine units that you are given. A variation is to allow War Pigs, or to replace zealots by stalkers.
Hardest difficulty completed: -
No Upgrades or Research
Hardest difficulty completed: Seems to have been completed on Brutal by Feb (?).

Marines, SCVs and Zealots only, No Upgrades or Research
No mercs allowed. You can use non-marine units that you are given. It's both previous constraints simultaneously, except that making scvs is allowed.
Hardest difficulty completed: Shiladie seems to have gotten stuck on All-in brutal.

Cloaked Units Only
Here you have to unlock ghosts or spectres ASAP and from then on you can only make cloaked units (and scvs I presume). Uncloaked units that you are given can only be used defensively.

No Units
You are not allowed to make any units whatsoever, or call in Mercs.
Hardest difficulty completed: none. I expect this to be doable on Normal.

I don´t like multiplayer
Finish the campain (from evacuation onwards) without using a unit that is also in the multiplayer part (scvs excluded).
You are allowed to use:
Firebat, Medic, Goliath, Vulture, Diamondback, Spectre, Wraith, Science Vessel, Predator, Hercules
Note: There seem to be two variations: either avoid prophecy missions or also allow all Protoss units. Should be doable on brutal.

I don't like SC2
You can only use starcraft 1 units:
marines, firebats, medics, vultures, tanks, ghosts, goliaths, wraiths, bc's, sci vessel, and dropships. Zealots, high/dark templar, carriers, etc.
Note: Should be doable on brutal

Out of the box
You're not allowed to, with exception of forced circumstance (like the very first mission) use the unit or building introduced in that level. Once the forced circumstance is gone (the banshees clear the landing zone in Supernova for example) you must in fact destroy the "introduced units."
Note: The Odin should be considered a hero Thor, so you must let it be destroyed without it doing any unnecessary damage in Media Blitz.

Choose
Choose ONE unit for every mission where you can make units; make only that unit and SCVs. You can get the mercenaries that match your chosen unit, but you can't use the same unit twice.
Note: You will mostly have to make the featured unit of that mission, making this pretty much the opposite of "Out of the box".

Sky Terran
You only train air units. You only train mech. The missions before you have access to air units are excluded (but you have to get air units asap). You can train SCVs.
Note: Should be doable on Brutal.

Mech only
You only train mech. The missions before you have access to mech are excluded (but get mech ASAP). You can train SCVs.
Note: Should be easily doable on Brutal.

Pirate mode! (RELEASE THE GRACKEN!)
Marauders, Vikings. I know both are kinda far apart in the campaign so substitute marines until Safe Haven/Smash and Grab.
Note: Do this on Brutal, dammit

The following are interesting but considered unrealistic until someone manages to actually do this:
You only live once
Complete the campaign without losing a single unit. Buildings are expendable but every unit must survive.

Note: this is going to be extremely frustrating, even on Normal. You can't do Utter Darkness. Good luck trying to prevent Kerrigan from getting any kills on all-in. But it might be possible...
SCV All-In
You can train anything, however only SCVs and structures can get kills. This does not include when you cannot train/don't have any SCVs.
Note: Oh, and you're not allowed to build units, then destroy your cc, and then attack The idea is obviously that you bring down enemy units to near-zero health before engaging with your SCVs. On all-in to reduce the amount of micro required you can use hive mind emulators to grab units quickly, and planetary fortresses. You can only use turrets vs air units! I'm not sure which is worse - this or You only live once.

Bei der Kreation "einzigster" gebe ich dir allerdings Recht.
