If the cheat engine was set for Virtual Families, that could be precisely why you are seeing the increase in the bank.

You may not know that using any form of cheating software is done at the player's own risk. Using cheats can and will cause a game to get messed up or become unplayable.

So, should I have her completely uninstall it from the computer? Or just make sure that she's not setting it for my game?

I'm afraid I cannot advise you on how to handle software from other companies.

If it were me, personally, I would have the software removed entirely, since I would be unable to determine if it was affecting any other program on the computer.

'Kay.
I'll do that, thanks.

Once my computer was updating some software while the game was running and I suddenly got a ton of money. That didn't seem fair, so I started the game over.

I do wish the money was divided equally among all the children. It would make the game more interesting and a bit more challenging. And take away the interest on the money. Nobody gets that high a rate in real life !!

Also, why no upgrades for the bathroom, the laundry room, and living room?

I reckon that there should pershaps be a sliding scale for the interest. At the beginning 10% per day is fine, but it should be reduced to almost nothing as the game goes on. At the start, the family might have, say, $500, and the $50 interest is useful. After several generations they might have $5,000,000 and so "earn" interest of $500,000, which is far more than any family can get through working.

There are of course no whole-room upgrades for the bathroom, the laundry room, and living room, but there are individual items that can be bought, like the scales and heated towel rail, the treadmill, the flat-screen TV, etc. In addition there are lots of user-created mods that can be used.

I'm guessing that at one point if you're too rich, even if there are lots of other upgrades we'll just buy them in a flash. Maybe it would be good if we could build extensions in the house.
