If you want to make a game (or any piece of media) set in the modern world you need to have a really good reason for it. It's difficult to create compelling stories within a modern environment since many people play games/read books/watch movies as an escape from the real world. They often don't want to be presented with the same problems they might encounter in their own lives, they want something different.
An obvious exception to this is when you take en existing story set in a different time period and move it to the modern day, which helps the viewer/reader/whatever better relate to the themes of the story by viewing the characters in scenarios they're more familiar with.
