Making currants is way too easy. OK, it can be a bit tricky in the very early stages of the game, but it doesn't take very long to get to the point where currants become pretty much irrelevant.
For example, I finished the test yesterday with a total of 168,735 currants - I would have had even more if I hadn't bought a ridiculous amount of potato patties off Cupcake right at the end. There's no point in having that much money - there's really very little to do with it. I already own a 50K house in Alakol, and there's pretty much nothing else to buy that would even scratch the surface.
The thing is, I started this test with just under 100,000 currants, and a few days later am well on my way towards doubling that, and I wasn't even trying very hard. I was even working (in real life) all weekend, so I didn't really get that many gameplay hours in. Everyone says mining is the easy route to vast riches, but I didn't go down that road, I just did a little gardening and cooking, selling stuff to vendors and at auction. If I'd spent the time between crops going down the mines too, I can't imagine how much I would have made. At this rate, it should be trivial to break a million before the reset.
It seems to me that there's still a bit of tuning needs doing here. Once you've got all of the gardening skills, for example, it's very easy to churn out vast quantities of vegetables - especially in the large Alakol gardens, and each time you harvest or plant, you get a ridiculous amount of music blocks and game show tickets. Just selling the music blocks alone generates a sizeable pile of cash. Making money was fun for a little while, but it's getting a bit boring now. There's no challenge there. It's just Farmville, but without the tractor and annoying gifts...
I'd like to see either making currants get substantially harder as you progress, or have living costs get significantly more expensive. It should be a balancing act to make enough money to do the things you want in game, not just a case of shovelling currants into the vault.
