Any ideas if the"other PC platforms" will even crossplay? I know Steam has had some MMOs that had Steam-only servers while others older MMOs they'd did not. PSO2 is meseta pso2 a game which is based around cross platform much in precisely the exact same manner as FFXIV. Steam includes. Unsure about Epic, Uplay or even Origin though as if it's coming to any other"PC platforms", it will be those ones.
I can't see it coming to ones such as GOG Galaxy, Itch.io, Bethesda Launcher, Battlenet or the Nexon Launcher (although GOG Galaxy and Ich.io for different motives from the remainder of course, those two are far more indy-oriented while the other three are too proprietary-focused and not as well known for being storefronts as much as they are the way you play with Phantasy Star Online 2s from those publishers). Perhaps the Discord Store and Twitch program? (those are worse compared to Epic and Origin, therefore I've doubts (the Discord Store is even dead, makes me wonder if they are still selling games in the Twitch program )). What else even is there anyhow?
Assuming the situation that is improbable the EU version is not server and a distinct client. I really don't see why not? The way these things work. It would only be the NA version, we'll be lucky if they give us EU-hosted ships as a substitute or other languages (contrary to popular concept, a game doesn't have to be localized to European languages to release there, many Sega games including Yakuza are available only in Japanese and English all around the world). In Terms of Steam. PSO2 has replaced the SEGA ID system for Microsoft accounts. Microsoft has been trying to expand Xbox Live to additional platforms like Switch and PS4 for specific games. This is already the case with Cupheads on Change as well as the many platforms that Minecraft is on.
If this goes to pc platforms is or will Windows 7 consumers eventually be able to play with it? First off. Even the JP version dropped official support for Windows 7. Second off. Probably not. The SEGA ID program had been replaced using Microsoft's Xbox Live authentication features are tied to the Xbox Game Bar. As of now, Halo: Master Chief Collection and Sea of Thieves need players login using their Microsoft / Xbox Live account amounting to a distribution and upgrade platform.
Consequently, the same may end up happening with Phantasy Star Online 2; the Steam version would nevertheless require you login with your Xbox Live account. Nevertheless, I am not sure whether buddies list will remain Xbox Live only since they seemed to have'future-proofed' it buy pso2 meseta xbox creating"Xbox Live friends" a tab at the menu... or it could just be strange UI design, who knows! In the event that you buy the Steam version you may play with with Halo: Master Chief Collection on Windows 7. The Xbox Live authentication happens within Phantasy Star Online 2 so no need for Windows 10 Xbox functionality.
