When creating worlds we found it was fun to have different rules for land and space (or land and sea) because it felt different to be in a space ship than on land.
You have to be careful when making HarmoniousWorld.com cards for both space and land because they are different. When you are in space (or sea) your characters are on a ship so the card must reflex this. Another difference is that in space battles you use the ship’s power as well as the character’s abilities to fight and on land, you use your character’s strength, weapons, and abilities. So it is important now to mix up the cards between land and space. Here are some example cards for land and space
|Land cards||Space cards||difference|
|Items/Supplies||Heal + 1 each turn||Repair 1 hull each turn||Because you are in a space ship you repair the ship|
|Treasure||Glowing gem 1D4 2< cursed else causes villains to flee||NA||No treasures in space.|
|Quest/Mission||Repair Civilization 10 spaces 20 gold||Set up space station 10 spaces 20 gold||There are no space station on land|
|Event/Situations||Strange creature if communicate 1D12 5< shows next two cards else attacks||Robot if communicate 1D12 8< shows next two cards else attacks||There are no robots on land|
|Anomaly||NA||Blackhole 1D20 12< moves you 1D12 spaces||There are anomalies on land|
|Trap/Hazard||Mines! to avoid 1D12 damage||Asteroids! to avoid 1D12 damage||There are no asteroids on land|
Try to make even the smallest detail reinforce the players are in once environment other than other, For Example, in space, you are allowed to have more characters and pets because there is more room in the space ship. Because players can carry lots of other NPC you can make pets are more common in space and sea.
To make it easier to find cards, you can make land and space cards different shapes. Like land tiles square and make space tiles a hexagon.
Some cards don’t change like clues, treasures, and civilization. They are the same in both land and space but most cards are different. You also roll the same dice.
May the dice be in your favor.
