I have an idea about a modern-day war game, where players build up their base and attack other players. What I was unsure of was if a game like that needs a back story, a reason why everyone is fighting each other.

So what do you think? Should a game with base building and PVP need a backstory? If so, what are some appealing ideas?

Why is the world at world? How do new players coming into the game change the story at hand? If at all?

Will there ever be a single victor? If so, what happens then?

Let us have a discussion...

First, you might want to do some research on why people fight each other in the real world. If you spend time learning about real conflicts and wars and why they are happening, you will undoubtedly find inspiration for a plausible and relevant backstory for your own game.

A good place to start might be this wikipedia article listing current ongoing conflicts in the world.
