having stuff like that would be really cool. but it'd only have serious effect if u found that in a doctors office filled with blood and bodies. but stuff like this littered through the world would really bring the world to life
you gotta think about how many buildings you want / how much variety and you need to more or less calculate the spaces they take up when doing the map etc this map took about a week to do completely and the mainstreet building ive shown were 12 hours collective work on and off but
you may as well find a lot of enjoyment from making a map / designing buildings and you may just end up making the biggest ever map for pz featuring an 1:1 recreation of atlanta
in the end id say just go for it, dont let anything or anyone tell you "its too hard and time consuming to do"
atoxwarrior's right pretty much its a hard task but if you have the freetime or just determination on hand you can do it easily, its just a lil frustrating at times when things dont work out or the guides dont tell you everything and you gotta figure stuff out yourself
