embedded windows in the japanese arcade scene has been working fine so far. for example, most of bandais arcade machines in the past like 7 yaers or so basically run embedded windows.
it was a benefit to non arcade users because a majority of games that were on those machines eventually got pc versions, or a new game on pc for the first time (e.g Tekken 7, Taiko No Tatsujin), where historically, theyve basically never been on PC officially.
