Strengths:
- Deck builders are always popular, and I think your proposal has plenty of potential for wide appeal. There's plenty of directions this can go, and Currency, Lives, and Disasters seems a good starting point to build on in terms of the resources and conditions to manage.
- I love the artstyle you've focused in on, I think your game will have a really distinct and appealing identity a it develops.
- Incorporating misinformation into your game is, I think, a good idea, and would give the player options to do things that might feel right but have repercussions and knock-on effects that are themselves educational.
Things to consider:
- A card game is ambitious, but definitely doable; one particularly polished one won last year. Still, you'll have to be organised, and you'd benefit a lot from getting some core mechanics ready for the prototype to have early feedback and playtesting. Try to work towards a minimum viable product, that you can then polish and expand in the production phase.
- Thematically, I think you'd benefit from ironing out what is you want your game to say, and how you're approaching the theme. For example, in a game where you're tacking disasters, using currency as a resource would presumably incentivise relief measures that also create more of that currency resource, which is a focus that, in real life, causes govs to invest huge resources into precisely the companies causing the most harm (eg, lots of renewable energy megaprojects involve funneling money into petro-chemical companies), while also spurring consumption which is itself harmful. But maybe I'm misunderstanding scope; your call to action is "Raise awareness of the effects of everyday actions most people can have", so perhaps having the POV of, say, a community relief effort rather than a government would allow you to best serve this CTA without the risk above. Zeroing in a POV like this could also give you more interesting things to say, and dynamics, for cards (eg, beyond expecting messaging like litter picking, at a local level like this, protecting the environment and recovering might actually involve fighting *against* companies wanting to invest in infrastructure, even green infrastructure, which might harm struggling wildlife). Either way, I think further brainstorming about how you stick closely to the theme as you develop will be really rewarding in terms of both having a clear message and having a more unique viewpoint.
