Floaty boats card game
Actually spaceships
A ship seats 3-8 players

Ship classes: 3=frigate, 4=corvette, 5=destroyer, 6=cruiser, 7=dreadnought, 8=titan

Each ship has an energy pool, an external deck, and an internal deck for each player. Also a damage deck.

Has 4 roles (3-seat ships lack a role)
Four roles are commander, pilot, gunner, engineer
Every ship has exactly one commander
Pilots can be scanners or controllers (or none)
Gunners can be light or heavy (or none)
Engineers can be energy, propulsion or shields (or none)

Every role should be playing a different game but I don't know what that looks like yet.
Especially because sub-roles' games should be similar enough that they can merge, but different enough to be each interesting in their own way. Some extra rules/zones if it's specialised, basically.

Each turn is played in two phases:
Ship phase, where players perform internal ship actions. This phase is timed.
Commander phase, where commanders meet and perform interactions with other ships. This phase may be timed.

The game, usually, ends when only one team remains standing, but this may take a long time, so for quicker games all players should agree on a fixed number of turns to play at the beginning, and adjust it with all players' agreement during as they see fit.
Scoring at the end of the game involves subtracting damage points from trophy points. Ties are broken first on player count (fewer players wins), then on total energy (more energy wins).

Have to handle the scenario where a particular seat has nothing to do because it's not in use; I think their cycling should lock up, it makes sense, but they need a way to still be in the game despite it. Maybe repairing damage? Training is also an idea: Skip your turn, improve your deck.


Rough deck sizing stuff:
3-seat ship ~30 cards per seat + 3 shots live (10 cards/shot) = 120 cards
Each seat plays 2-3 cards/turn from a hand of ~5, initial deck maybe 12-15 cards gives 15-18 upgrade slots
Damage deck = ~15 cards = 135ish, plus misc = 150 tops

8-seat ship ~50 cards per seat + 20 shots live = 600 cards
Each seat players 5-10 cards/turn from a hand of ~10, initial deck maybe 30 cards gives ~20 upgrade slots
Damage deck = ... 60-80 cards? plus misc = 700ish
... Allow up to 800. Maybe grow seat decks a bit, allow them to upgrade multiple cards per level.

700/150=4.666666666666667 so you can fit nearly 5 3-seat ships in the same space as an 8-seat ship.
800/150=5.333333333333333
Plus 3 egg-timers per box - that will probably be most of the space tbh.
