Business sim games that are actually challenging
I just booted up Jurassic World Evolution 2 and was struck by how easy it is. Snatch a dino, put it in the pen, drop some rocks and trees in there, print money, repeat. If there's something you can't afford, put the game on high speed and wait. Then you can afford it.
Good Company was kind of the same. Once you design a product and have your production set up, you're just waiting to make enough money to design a new product and do it again.
Software Inc is the same. Once you've got a couple releases under your belt you literally can't spend money fast enough.
Really I'm looking for a game where you are making hard decisions about your resources, time, and focus. Where there are stakes. Does anyone have suggestions?
