Which happens first. Picking Objective shifts, or moving the obstacles?

Both occur "after deploying fleets"

First player goes first. First player decides in what order to resolve his simultaneous effects.

Hmm. That brings the following question: Who is the owner of the Advanced Gunnery effect? (I assume it is a single effect "players should select Adv gunnery ships, starting with the first player" and not two separate ones "first player selects adv gunnery ship", "second player selects adv gunnery ship")

It is a both player effect with the timing laid out.

It's not clear from the wording of the effect (given that there is only one trigger). In fact I would go with the interpretation that it is second player effect (as it is his objective) that will make everyone (starting with first player) to choose ships once triggered.

Pertinent Rules portions:

Setup: After deploying fleets, each player chooses 1 of his ships to be an objective ship, starting with the first player.


After deploying fleets, you may move each obstacle at distance 1-3 of that token to with distance 2 of that obstacle's current location. Obstacles cannot overlap tokens, obstacles, or ships."

During the “Choose Objective” step of setup, the first player looks at his opponent’s objective cards and chooses one of those cards. The chosen card becomes the objective for the game ;

• If two or more of a player’s effects have the same timing, that player can resolve those effects in any order.

• If both players have effects with the same timing, the first player resolves all of his effects with that timing first.

I believe:

If the Grav Shift Reroute is owned by the first player:

They may Choose their objective ship, or move the Obstacles... Their choice first. Once both are done, the second Player chooses their Objective Ship.

If the Grav Shift Reroute is owned by the second player:

They may choose their Objective Ship, or Move the Obstacles, but that will happen after the First Player has Chosen an Objective Ship...

The 'interrupt', for lack of a better term, is provided because you have to account for all of your effects...

Additionally, the Objective is not a second player effect, even though it comes from their choices... because once it is chosen, it becomes part of the game's effect... The rules provided show the subsequent effects generated by that objective...

First player goes first. First player decides in what order to resolve his simultaneous effects.

Then second player goes. Second player decides in what order to resolves his simultaneous effects.
