Quoting tesb, reply 3are you going to fix the inorganic look problem in the future?
1) the regular ground cover between buildings
3) merging of buildings
otherwise it looks good, release the new beta already
2. I'm not sure what you mean. We do want to have buildings that if placed adjacent increase the adjacent building's production. I.e. a windmill next to a farm increases the farm's output. We want to keep these relatively rare and they would be improvements that would come in pairs or groups so that players aren't having to remove improvements because they don't have a spot for the new one.
Glad to hear it, especially with regards to #1 - all you really need are some cobblestone streets or something similar between buildings, and it'll look much more integrated. More like a city than a dozen buildings sitting on the grass next to each other. [Would also be nice if the outside roads connected in to the city's street network, rather than running diagonally through existing buildings as in the screenshot ]
#2 sounds fine as well, I can live with adjacency as long as we're talking about buildings available with the same technology that we can build at the same time, and never end up in a situation like "I just researched these new windmills, now I need to go find every city with an old farm and demolish some buildings to fit them in."
