3D Architecture App

I am trying to make a first person shooter so I looked up unity and thought you could build or somthing but you walk waste of time

This is a very stupid game what are u pose to do it is hard to control and it fells like that something is going to pop out do not get it???????????????????????????????????????

This apps isn't worth the time.

There is no point to the game!!! I mean you look at a green house and that is it!! Do not get this game!!!! It's a wast of space!!!! I ? on you creator of the game!!!!!!

What are you suppose to do, because I thought you could renovate the building or something...
