I'm thinking that this could be added at any point in the game's development really, but pretty please can we have some new ramp styles which represent roof tiles and even hay/ thatched roofing. I see a lot of medieval-style builds, and they look absolutely awesome. I just think that giving us some actual roof-specific textures, would be a really brilliant thing to do. I would love to see loads of tile types of different colours, and a few variations of thatched roofing, and perhaps a few unique ones from the guys' imagination.
I think overall, the game need more things from imagination. if it's all about the real world, then it'll lose its appeal for most players very quickly in my opinion. Please don't get me wrong! I absolutely love the game, and where the devs are taking it, but i'd really love to see a lot more imagination thrown into it, rather than things which are expected in reality.
I'm just saying that, probably, 70% more players would buy this game if there was some kind of imaginary/ fantasy edge to it. It doesn't have to be super over the top dragons and knights riding flying unicorns into haunted forests full of demons who throw their own heads at you. I just think that it can still be ultra realistic, but it need that extra something to make it truly interesting. haa!
BTW-I am aware that the physical appearance of the please makes no difference. Haaa!
