What about spas on a special street (not just standing near an energy well)? They would have a special effect on energy and mood that wears off after some time. It could also be a fun meeting place.
I like the idea of spas--it reminds me of Animal Crossing, where you go in and get a new hairstyle by answering a series of questions asked by the hairstylist--the style you get depends on the combination of answers you give.
re: energy wells--don't forget if you advance enough in meditation, you can radiate peace/joy/beatitude and everyone on the street will get an increase in both energy and mood. And you can focus and increase your own energy and mood.
@Dryea Well it's not much fun just "standing" in the area with a pool of water watching your energy bar. There could be some cool animation, mermaids giving massages and such.
I like this idea, but there has to be something to prevent people from just abusing it all the time when they start feeling tired. Like maybe a "pruning" moodlet or feeling dizzy and lightheaded from staying in there too long.
