Key word to tutorial
tutorial It's a good tutorial as in it gives them a break down step by step on what sort of patterns and ways of doing it. It would be nice if it also had a section of things you dont do when making a level etc.. but for some one who wants to try to make an outside level its really good. I might try to make a level going off this tutorial and see how it turns out.
As for a town tutorial. I might do that when I get some free time it shouldn't be to hard. Most people's problem is color scheme. They dont have any theme's they do one type of house then another bright colors dark colors. They need to use colored tiles that are at least similar. Either all sorta dark tiles or all bright tiles etc..
