Have you looked at Create? Disclaimer: I’ve never actually played it myself so I’m not sure if it’s exactly what you’re looking for

I think I mostly agree with the things everyone else is saying here. The only thing I’d change from your PCPartPicker list is to bump the CPU down to a 9800x3d and upgrade the GPU to a 9070xt

I see you have some questions about PSU. Here’s the PSU tier list. For the level of machine you’re aiming for I would only recommend A tier. For wattage, take the expected wattage from PCPartPicker and add a couple hundred. With the changes I suggested that’s a minimum of 750w for you, but I think I wouldn’t go lower than 850w
