Summarizing our progress so far...
Alright taking into account the thread progress I revised my original template trying to include the changes desired:
Art of war
Guns/Canons/Gunpowder: Early Cannon and Fireworks
Calvary: Heavy, and on rare occasions other beasts
Heavy horse cav: yes but expensive to waste
Calvary dominates the battle field
Armour: All the way up to 16th century plate (because that stuff is boss)
Hand weapons: All stuff until 15th 16th century
Missile weapons: Bows, more expensive; x-bows. Expensive and rare; other more advanced kinetic weapons (repeaters etc.)
Magically assisted weapons: Yes
Warrior codes: Advanced (bushido, chivalry, warrior societies like the Knights of Malta etc.)
Navigation and travel:
Compasses: G node compasses, no magnetic north compasses. Celestial navigation still possible obviously.
Chronometers: No, crude inaccurate mechanical clocks at best.
Dominant propulsion: Sail
Alternate propulsion: Yes
Steam: No, to very minor experimental use in small enclaves.
"Boat" types: Up to 15th century sail technology, i.e. Caravels
Airships/airtravel: No to airships in general, yes to limited (i.e. rare) magical conveyances and tending to range on the small size.
Flying creatures for travel/transport: Yes, anything. Rare.
Overland transport: Wagons, horses, etc. Possibly landships for special uses
Postal/carrier services: common for upper class.
Writing and learning
Printing press: No
Scholarship level: 15th century?
Learning institutions (eg. universities): Yes.
Heraldry: Advanced, still important.
Observation equipment: Crude telescopes.
Industry
Power sources: Wind/water flow, magical
Cam driven processes common (trip hammers, felters etc.)
Lathes: Wood only
Metallurgy: Steel is "common"
Cast iron possible, though inaccurate
Bronze casting is fairly accurate
Bell/cannon casting unreliable but common enough
*Note 1: Note this list only indicates the functionality of the technology achieved, not necessarily the actual technology.
**Note 2: Any early technology is obviously included here, and these listed technologies only represent the most advanced they have reached in the most advanced nations, which, obviously, large portions of the world will not have reached. I mean more than half the world was still fighting with pointy sticks while Europe was busy running around with guns.
***Note 3: We can obviously artificially stagnate or halt to quick advancement and keep our world in the same stage as long as we wish, or not depending. Obviously we are going to develop it at one fixed time for now so no need to worry too much about consequences.

If there are any changes you'd like to see to this please bring them up for discussion. Especially since it's almost exclusively my list at this point, lacking any others to go on.
