Just thought to confirm the bold and underlined section is 100% inaccurate.
You'll find a good bit of gamers who own both a gaming PC and at least one console...but in terms of using a gamepad on PC, well some games require it so that's also inaccurate.
I had to quote and reply as I'm an early adopter on the xbox one but I've always had a gaming PC and just upgraded both to a new gaming PC and the Xbox One X this year.
*On TOPIC*
-From reading in many different forums, what I've found is not that games should offer cross-play but that customers like the idea of a developer who will allow it. In practical terms, many games should but when thinking of a flight sim or FPS, MMO those games and their interfaces and keybinds often bring up valid points of concern as to why it "should not be offered" widley.
Each game will have its own value towards and against why the developer should or shouldn't offer crossplay.
I would argue strongly this game is one that shouldn't offer it primarily due to the fact of VoIP, and peripherials and keybind limitations/offerings.
A funny observation tho, within a game I use to play a ton of, Elder Scrolls Online.
They have leaderboards and one of the hardest parts of the game that also offers universal scoring for individuals and group PvE content...in each category the group content was mainly even comparing PC to Xbox One for a couple of months.
In the solo PvE content, the Xbox One players had the best scores for over a year compared to PC and PS4...so whats funny is mouse and keyboard aren't better than a gamepad. In this specific example PC also had access to add-ons and UI customizations and extra info never available to Xbox One players in addition to being locked at 20-30 FPS on xbox vs 100+ on PC.
