developing a fighting game is possible or not in unity.?

Hi All,
I am new to this technology, i developed some small games. I am about to do a fighting game.let me know is it possible or not.?

Anything is possible, if you wanted to fight dinosaurs in space using nothing but ukeleles you could. If you can elaborate more on your ideas maybe we can help identify things you may have issues with.

What were your original concerns that brought you here?
