Andy and I were trying to figure that out. We’d figured it wasn’t 5Gs because of the size of the planet, but we didn’t know exactly how that worked. We’d figured it would be about 2Gs in the end which would be far less impressive.

The addition leg thing may backfire. With legs like a horse or an elephant, you have increased free standing body mass that sits between those legs. That means your spine must be incredibly strong to support it. It would be far easier to have two legs (or one) and suspend all the body mass above them. You’d need far less structural support.

Shorter works better here as well. Dwarves would be the norm, I suspect.

How do you think it would work in a legless, water world?

my thought is that sophonts will have three legs around 1.5 gees, and four legs (i. e. centaurlike) at two.
