Windows 10: cross-platform play questions

I do not own an Xbox one or an Xbox 360, but my friend has an Xbox 360 and I have a windows 10 gaming PC. I was able to add him as a friend and send messages, but I see that a number of games do not show up in the windows 10 or Xbox one section of the store through the Xbox app or the windows store. So I have a couple of questions that I could not find any answers to through google.

First off, would a windows 10 PC be able to play games online with an Xbox 360 user?

Second, is it possible to do the cross-platform play if I do not own any Xbox consoles?

Third, will the steam versions of the game work for cross-platform play? Or must it be purchased through the Xbox app or windows store? (If through the Xbox app, then would I look in the Xbox one section or the windows 10 section?) [If through the windows 10 section in the Xbox app, would the Xbox one section games be playable if bought without the console?]

Fourth, If I am understanding correctly, older games (most on Xbox 360) will not work for the cross-platform play, and newer games (most, if not all on Xbox one) would work for cross-platform play?

fifth, regardless of my specific situation, would GTA: V work for cross-platform play with windows 10 to Xbox live players?

Thank you to anyone who takes their time to read and answer all my questions!

Cross Platform Play

Hello there I had the same issue and what I did was I had my friend log into his account on a PC with the Epic Games Launcher so I could add them. (It was for PS4)

Hope this helps and good luck.

 

Cross Platform Play

I've recently been trying to play with my friends who are playing on XBOX in Fortnite, while I'm playing on PC. Is there a setting on my PC that can help me allow this or is it all through Epic Games?

 

As far as I know the XBOX app for Windows 10 is not actually for playing games on the PC. It is more like a remote desktop client for the xbox (either xbox one or 360). In other words you actually have to remote in to the xbox one or 360 - it will not play games as a standalone device.

 

So does that mean that cross-platform play for any game would not work since I do not own an Xbox? Or just that the Xbox app is not essential to the cross-platform play and I do not need an Xbox?

 

I am 99% certain that cross-platform play for any game would not work since you do not own an Xbox.

 

Okay thank you very much for clearing that up!
