I'm re-doing the wall with the door to my utility room right now, which is mainly for the 12 foot bar I built along that wall. This wall was previously painted red, the other walls light brown, but I'm going to move the door location and make it bigger (allowing another machine in the game room, and a wider, easier door for moving machine to and from the fix it room), and then do some type of brink wall there.
I looked at the faux stuff, but I usually like to keep everything somewhat real, as it rear wood, and at least some type of real stone. I found the layered slate that looks like brick at Home Depot, and I'm thinking about that, but trying to see if there is anything else interesting out there. There is a McDonalds near me that has used a very nice brick covering inside, I wish I could find it.
I like some type of brick for a one wall accent though, it always looks sharp, especially in a gameroom.
