A bunch of us have been putting together pictures of hair/clothing/furniture we'd like to see. But I'd like to zoom out and consider the theme as a whole.
Challenges and choice: Being environmentally conscious is a choice, so I think this pack should come with choices to make. Do they want conveniences (less Eco) or are sims willing to go the extra mile in order to be Eco? Hand washing/using a clothesline takes longer than setting a machine and walking away. Cheap washers aren't going to be as Eco as expensive ones -unless you can upgrade them, and they would still be less efficient than the top model.
Innovative home technology and price: Solar panels are an excellent way to make your own power and reduce bills - but they are generally expensive to buy. Should each panel cost upwards of $10-15k? Such technology, while saving money in the long run, is usually a little cost prohibitive upfront to implement. Additionally, there may be a super efficient washer that is very expensive, but when upgraded fully, it could use less water than hand washing.
Which means sims starting out (sans motherlode) will have a goal to work towards. Their starter homes won't be maxed out and Eco-living is something they must actively pursue and implement in stages by installing piece by piece.
Formula for bills: Home technology maybe cost prohibitive, but there are usually tax breaks for implementing energy efficient appliances. So if home technology (like solar panels) were to be expensive, I would propose that they either be excluded from the household bill formula or receive a dramatic reduction in their "taxable" amount.
What are your thoughts? What would you add to the playability?
