Well, here's the rundown of iEra:
Ways to make money: digging for shells, killing crabs, picking up trash, picking flowers, making pizzas,and mining.
Entertainment: gang wars (same as guild wars on iClassic), the astro bar (you own this if you have the top guild of the week/month), and various quests (like the alien hunt or the End of the Universe.
Events!!! There is now an "Events" system added to the app with games such as musical chairs, hide and seek, race, etc. All are pretty cheap to play except for hide and seek, which gives you an item if you win.
