I had not heard that Microsoft had decided to release Xbox titles for Windows 10. For many years I had held out hope that they would continue to support PC gaming but after GFWL dried up, I realized that they were focused on Xbox and since that made the most business sense, it was no surprise. It also fit Microsoft's long established habit of abruptly pulling out of various hardware and software ventures (Zune, networking, peripherals, etc) when things weren't working out.
I wonder if their getting back into PC gaming is a sign of how they view the long term prospects of the consoles. I think both Microsoft and Sony had dreams that the console would be the ultimate hub for all gaming and media in the home but there are just too many other devices and services picking away at that vision.
Yeah, they’ve basically returned now. Windows 10 gamers do not need an Xbox Live Gold membership either to play with their friends on the Xbox One, it’s completely free. Cross platform play is currently available on Gears 4, Halo Wars 2 (some modes), Forza Horizon 3 and Forza 7.
As for the system requirements I mentioned, the Xbox games require a powerful PC to run so I think this could cause problems for would be buyers as not everyone has a high end PC.
I agree. In my opinion, all gamers should be able to play together regardless of the hardware in third party games, with 1st party games remaining exclusives. The only exception would be the PC, whereby some genre’s (FPS/RTS) may be difficult to balance competitively without allowing console users to use a M+K as well. Alternatively, a small warning that users are about to join a cross platform playlist could suffice. I’m glad Fortnite and Rocket League have attempted to reach this goal (Xbox, PC, Switch) as well as Microsofts push for this as well with their Cross-Platform support (Xbox, PC). I would love to play Halo: Infinite at native 4K, HDR at 144hz with my Xbox friends.
As for the OP:
- Physical copy only. Can be found easily for purchase. Current version of the game is 1.10 - supported by Bungie and the Halo PC community.
- Physical copy only. Due to a smaller print run, this version has a higher average price than Halo PC. Can play with PC players when patched to latest version.
Halo Custom Edition
- Free download that allows for additional campaigns, custom maps etc. Requires a Halo PC CD key to install.
Halo 2 Vista
- Physical copy only. CD key can only be used 5 times before it cannot be installed anymore. Be careful buying a used copy as a result of this. Official Multiplayer servers are currently offline though LAN and Campaign can still earn you achievements.
Halo Wars Definitive Edition
- Available digitally via the Windows 10 Store or through Steam though Windows Store players cannot play with Steam players, be warned of this. It is NOT cross platform with the Xbox One version.
Halo Wars 2
- Windows 10 Store only. Supports Cross-platform play for campaign and some modes with XB1. You also will get a digital copy for XB1 when purchased.
Halo 5: Forge
- Windows 10 Store only. Has its own unique achievements. Glorified Forge mode with a custom games browser. Free to play.
Hope the above helps.
