One of the reasons why we bought ours was because of the basement. The plot of land looks like they built it up a bit--and they must have gone to town on drainage around the house. Some part is surely from digging the basement. No sump pump here--but we could that it had not had a leak in 20 years (age of the house) when we inspected it. We do run a dehumidifier in the basement, with oil fired hot water (and being underground) there is no getting around that. Small cost. The a/c running upstairs in the summer is doing the same thing, pulling moisture out of the air, to prevent issues.
Put differently: my 1,900 sqft house has a 1,900 sqft basement. Wish they had dug one foot deeper, even still, it's like 8' height. I put in a drop ceiling into my office and yeah, it's like 7' or whatever--I don't care, I sit in my office, and I'm well under 6' tall.
