Games that will only be on the Xbox One or Ps4 is a big deal both have there own games that you can only play on there console. So I am going to list the exclusives for each console, since i feel these are important. I want to start off with the Xbox One exclusives that you can only play on Xbox One or your personal Computer. I will also put a link to watch the trailers.
