Differences in top two plans:
Except where noted here, both plans are the same.
The Mariner (and relevant parts of the fall):
Most of the point differences between the two plans here.
Plan: Walk Softly, and carry a very big stick
-Small (2 points)
-Weighted Light (1 point)
Plan: Codex Vulkhari 3rd Edition.
-Armada (-2 points)
- Killing Blow of the Murdiously Shining Sword, Sword of Vaul class Relic Warship (-5 points)
- Escorts Broken (1 point)
Pretty huge difference here between starting with a small fleet and starting with an armada fleet larger than the major craftworlds. Especially when supplemented by the super ship, Killing Blow of the Murdiously Shining Sword, Sword of Vaul class Relic Warship.
The Smith and the Scholar
Plan: Walk Softly, and carry a very big stick
-Bonesinger Choir (-1 point)
Plan: Codex Vulkhari 3rd Edition.
-Seer Council (-2 points)
- Psychomaton Forge (-1 points)
Walk Softly, and carry a very big stick takes a Bonesinger choir to help build ships and other tech to make up for small starting fleet. Codex Vulkhari 3rd Edition. instead takes the seer council to provide future predictions right from the start and a psychomaton Forge to help (maybe eventually) offset the decimated population both plans also took.
Allies:
Plan: Walk Softly, and carry a very big stick
- [Smalls] Meros (-1 point)
Both plans took the same 2 minors as well. Walk Softly, and carry a very big stick specifically takes Meros as an ally to force the thread into an early war with the Orks. The plan's op has posted why they think this is a good idea, and with a 2 vote lead at the moment, it looks like we'll find out soon if they're right.
Major Craftworlds:
Plan: Walk Softly, and carry a very big stick
- [Alaitoc] Hostile Relationship (2 points)
Both plans otherwise took the same set of bonuses and maluses here. Worth noting that Alaitoc is on the far side of the galaxy, so if you're going to upset someone, they're a pretty safe pick.
Other Races
Plan: Walk Softly, and carry a very big stick
- [Necrons] Respect (-1 Points)
Plan: Codex Vulkhari 3rd Edition.
- [Necrons] Fear (3 points)
- These Worlds are Not For You (4 points)
Pretty big difference in approach to Necrons here. Notably, Plan: Walk Softly, and carry a very big stick does not take a stance on the miscellaneous minor races, unlike Codex Vulkhari 3rd Edition.
Location
Plan: Walk Softly, and carry a very big stick
- The Northern Edge (3 points)
Plan: Codex Vulkhari 3rd Edition.
- Watchers to the East (4 points)
A 3 pt vs 4 pt location. Which one you want is probably down to which set of canon timeline events you want to get involved in?
Tech
Plan: Walk Softly, and carry a very big stick
- [Tech] Power Weapons (-1 Points)
- [Tech] Holo-Fields (-1 Points)
Both plans take Grav-shields. Plan: Walk Softly, and carry a very big stick doubles up with holo-fields and also take power-weapons. QM has said that large vehicles will be able to double up and use both but implied that small vehicles likely won't have the weight/item slots to be built with both at the same time.
