Seasons

Introduction

GTA Online is a great virtual world. Currently it has sunny days, rains and occasional thunderstorms.
So I believe if four seasons can put up to the GTA Online world that would be a game changer.
Because the ecosystem of the GTA Online can completely change in a better and much more fun and attractive ways.

Complexity (Development)

As a software developer I know the struggle of developing these sort of complex mechanisms and
that’s why I want to narrow this down:

Implementations 

Spring and Summer 

When considering  the world of GTA Online, Spring and Summer is pretty much already there. 

So we need a little bit of tweaks here and there. 

Autumn

This is a little bit of graphical work. Changing the colors of tree leaves and fall throughout the season. 

Leaves can go by wind as an additional graphic work.
