It would be good if there were more locations and vehicles such as railway stations and trains, airports and airplanes and other similar locations, because walking around the city, which is not very different from others (ok skyscrapers are great) is a bit boring after a while. I know that something like that is probably an impossible idea, but it would help improve the game, it would be closer to the real zombie apocalypse. I'm playing 7 Days To Die since Alpha 10 and many of the buildings has not changed, so a few new buildings have been added, but they're still just cities with nothing special. Even if nothing would be added, it will still be my favorite game.P. S. Sorry 4 my english
Your English is fine, so don't worry about it.

And welcome to the forum.
On adding to the game, it would be nice if new buildings could be added, but I don't know enough about programing if it would create other problems to add or remove. I do know that there is going to be some changes in some houses, and it is possible they will add more buildings, they did when A16 was released so hopefully a few more.
I think a airport would be good, it doesn't have to be a big one, just one of those small types, like the one up the road from where I live. Just the two seater planes, maybe hold four are the type of planes that fly in and out. Something like that would have a hanger, couple of buildings for equipment and such, store a small plane in maybe, or whatever is needed to keep the runway clear. Small office building that would have the normal desk, bookshelf, filing cabinet and hopefully a bit more.
Have you checked out any of the mods? There are some great ones that you could check out. War of the Walkers is a really good one; has some fantastic builds, lots of different foods and loot, many different POIs, one town is a Asian town, beautiful buildings. Starvation is supposed to be a good one, lots of animals in it along with buildings added, and NPCs. I haven't played in any, but seen some videos and they are really good. Skippy(0033? can't remember the rest of his name) has created a mod and there is a new one, Ravenhearst I think is the name, and there are more I am sure that you could check out.
Crossing fingers that the fun pimps will check them out and maybe be able to use something from them, it would be nice to have a couple of buildings from that Asian town in a section of a city. And some of the recipes, loot and other.
I love this game too, but for those who have played it for a couple or more years it can get very familiar and older players want some spice added to the game for a change of pace.
