Geoengineering 101, first developed as part of the November Game Design Showdown, is now being developed into a playable game!
The main idea here is, as anthiasgames described in the GDS comment thread, "you are setting things in motion you may not be able to control." Based on the idea of manipulating the weather to hold back the worst effects of climate change, there's a two-round lag between when you secretly slide a card under the bottom of the Action Deck and when it is actually played and makes its effect and side effect.
Here's some concept art and cards. The basics are:
1. Temperature is increasing every turn.
2. Each region has a Habitable Zone and will collapse if temperatures or rainfall goes outside of that zone. At the ends of the habitable zone may be Red Zones, where certain cards may trigger premature collapse.
3. Three main type of action cards:
Blue: Temperature down, rainfall up
Brown: Temperature down, rainfall down
Black: Does something devious and also shuffles Action Deck.
If two cards of the same color come up in a row, side effects start happening.
4. Two victory conditions:
- Have the last remaining region
- Have the most remaining regions after all Oil Importing regions have collapsed.
Will do. Got a first set of cards and mechanics worked out and will be testing later this week.
