You didn't mention what the walls are.
If they are cement block, you can get mortar mix (not cement mix that has gravel in it). Then you can parge the inside of the walls, just like is done to the outside of the walls. Once dry, paint it with white paint for a more expansive look to the room, or whatever other colors you like. Then your walls will have a nice finished colorful look to them. Decorate according to the new look, instead of just cement block grey. A few higher quality artificial plants, or grow lights and real plants, rugs and furniture that don't tend to hold moisture or humidity, and you're on your way to a nice rec. room or bedroom or kids' playroom or even use part of it as early spring plant starter room (as we do).
One suggestion is that if the space and walls are really dry before you "plaster" moisten the cement block before parging. If the walls are too dry before applying the mortar, it might dry too fast and not stick. If it's really dry, get a spray bottle and spray the drying mortar a bit as it dries so it doesn't cure too quick.
