I think its good. I wanted wood floors in my basement. The flooring guys said to me that i would have to put a sub floor down first. Since my floor was very level, they suggested me to do a wood parque floor, then I picked out good pattern and had it installed and finished and also stained to match my upstairs floors. I did that in my bar downstairs and on the landing area to separate the stairs visually from the carpet in the basement. I have had it down for about eight years now and it still looks great! No warping and nothing looks different. I would say that I live where we never have rain, and when we do, it is a monsoon! We have never had leaking in the basement, so make sure of that, but it can be done.
Is your basement dry? Tape down a piece of clear plastic (like a thick painter's tarp) - about 2 feet by 2 feet using duct tape to the floor.
Let it sit for 2-3 days.
See if there is moisture under it.
If not, then you may be ok to put down a wooden floor. I would not use laminate, however! You definitely should put down a subfloor. Your best bet wood be to put down Dricore. A little more expensive than plywood but MUCH MUCH better in a possibly compromised area.
