I haven't noticed any increased depletion or decreased for that matter, but the little bars are so small that it's hard to register anything significant.
I'm at 10 on Bliss and 11/12 on the others. Same experience of having a surplus of 2 icons and the 3rd being rare to non-existent! I'm just letting them accrue by natural selection, rather than doing any specific repetitive action.
I've built two 'vacation' houseboats and am waiting to construct a park around the skatepark option. Other than that, the island isn't getting used much - though I may build a 3rd houseboat so I can relocate all 30 sims in an emergency. (That dam on the mainland is a secret worry!)
Haven't built houses near the volcano either.....
I'm surprised I leave home some days...

Distinctly unimpressed with EA.
Actively playing my old game for as long as I can.
