I think it has become easier due to what we can get from expansion packs. I love many of the aspects of them, but in the area of having to work to get the items you want? Get a Midas Touch elixir and everything you touch turns to gold. In six hours you can make a million dollars. Maybe you don't want to use the elixir, that's okay just plunk some money from the money tree. Getting too old to fast, your sims will die elders before your kids grow up or whatever you need to get done before then? Simple, the Fountain of Youth will turn you back to a YA. You want to just extend your life, not go back to YA, get some life fruit, that will do the trick.
Many of these ways are legit, but are still quicker ways. Create a pond in your backyard and stock it with fish that brings in the most and sit on your porch (so to say) and fish the night away.
Live in Riverview? Easy fishing, go to the hatchery and you don't have to worry about it, it like shooting duck in a barrel, the fish are real handy, no worry they won't be there this time.
Be a fairy, it helps in growing the perfect garden that lets you make money fast. Just use bloom and you don't have to wait for the plant to grow or reproduce; a wave of your hand and there they are, just harvest away.
I really don't feel bad about using the kaching money cheat or even the $50,000 one once at the beginning of a game. But the Midas Touch and the Fountain of Youth, I felt as if I was cheating in using that in a project game.
Hunting up gems and metals, flowers, seeds you have to work at it to make the money, get out and run around, get dirty, hot, tired and the "I need to go pee!", those are legitimate methods. That makes it a real earning method, not drinking an elixir and in just a few minutes of play time you are a millionaire.
That to me has made it easier. I haven't tried any of the dynasties or challenges, as they do look to difficult to me, too restricted, but in regular game play, even in a project story, it can become too easy.
I am going to set my own limits as I do a project story. Not everyone has the SN that really lets you get rich quick without breaking a sweat. WA makes it easier, but you have to run around and collect the items, so that it still work.
