I think adding the possibility of make concrete walls will be great. It will aloud the player not only to build something better (and stronger) than plastered wodden walls, but also to build more high-big buildings. (you know woods and nails aren't good for that, if you want to keep a realistic touch to the game) Also would be easy to add (I think) 'cause you will need only a "Bag of Cement Powder" (could be made like the "Plaster Powder Bag") a "Bucket with water" and a "Trowel". For all the youngest out there that's what I mean: Uploaded with ImageShack.com The lv. of carpentery to use the cement should be around 3 or so. I think that because I'm a construction worker in real life and if you in lv.3 carpentery can make a decent stairs (that are hard as hell to do with wood, let me tell you that!) you must be able to use cement. That's it guys. Let me know if is not new or whatever.. thanks!
