Will this upcoming modification be usefull?
 

hello all, i'm currently making a modification for this project, in which you need to build houses in order to have more pets (seeing it as their shelter or something like that)
for example: you register, before you can adopt your first pet, you must build a house.
each house can contain up to a X amount of pets, so users need to be sure of having enough of them~

but my question is: will it be usefull at all? (it works at least against fast-growing players by making the price higher with every new house)

i've made a simple working example with a small tutorial in ~5 hours (not much code, but hey, i'm a beginner~ ;P ) which does the things in the example (only when adopting a new pet atm..)
