Quoted from arcademojo:
You should really seal the block wall with Kiltz or some other sealer to prevent moisture and mold.
Thanks for the input guys. I'm out of my element on this but yeah talking with some friends that are experienced with this that are helping me we are insulating. Hopefully going to be done this weekend. Will be adding on about 150-200 sq ft to the game room which isn't much but with how congested things are down there it is definitely needed for some breathing room and another game or 2!
