Here's a game I was going to use in the recent Festival of the Fallen but nobody wanted to play. It's called Airship War. Anyone who has played the game Battleship will notice similarities in the rules. Basically, you have 3 Airships on a small 6x6 grid. Players will roll their initiatives to see who goes first and place their airships. On their turn, a player may move one of their airships one space either up, down, left, or right and then call out a space where they think an enemy airship is. If they successfully choose the right space, they hit, and the ship loses 1 HP.
Fighter Ship - Takes up one space and has 1 HP.
Battle Ship - Takes up two spaces and has 2 HP.
Dreadnought - Takes up three spaces and has 3 HP.
Here is a map I've developed for it using airships from Final Fantasy IX:
