All basements are eventually somewhat damp and carpet inevitably gets worse (allergenic, musty, moldy) in a subgrade situation. See how the carpet is doing a year from now after the summer humidity and late summer/fall rains and then make a decision.
When and if you replace it, use LVP (luxury vinyl plank) that looks like wood. Hardwood will not stand up to the damp and will be expensive. LVP is cushioned and insulated as well as waterproof, great for a playroom, and much cheaper than other options. You can read up on it and order some samples; this is emphatically not the vinyl flooring of old.
I was going to say the same thing. We put LVP in a bathroom and I love the stuff. Right now we have old cheap vinyl tile in the basement, but when we get around to replacing it, it's definitely going to be LVP with the cushion underneath for the added insulation.
