The Hamster King
Although a good ideea, you're still off the mark.
If instead of building wealth you build a worker and then sell it back, you gain more than 30%. Depending on the unit, you can gain up to 40% (I think it's with the landsknecht), and I didn't check all units.
So Wealth should provide at least 40%. If you lowered unit production costs and their resale value didn't drop, then you must make wealth at least 50% to just come even with building units and then selling them back.
Of course, selling units requires some time, but I think the micromanagement abuse shouldn't be encouraged.
I went with 25 for a couple of reasons. Partially to make it even with the science process, and partially for other reasons.
Resale value is a function of hammer cost, IIRC, so it drops automatically with hammer costs. Something I should check on however.
All that said, I agree that that exploit should be removed. I'm more of the opinion that the sell-back profits should be reduced, however, rather than buffing the process much more; Several of us have told the devs that the profits should be nerfed a bit, so we'll see. Until I hear an answer on that one way or the other, I won't make the change.
Building the 'change jar' improvement will also help with this after 10-15 turns or so. Try the laundry room tile, since that's where it tends to accumulate
I only have to buy a bit of beer. And provide use of my hookah (for shisha, nothing illegal people ) of course. Others are bringing some real liquor.
