Xbox's third-party strategy has evolved rapidly since it was first announced more than a year ago.Not only are new games like "Perfect Sound" and "Raiders of the Lost Ark" being released on competing platforms, but some of the most iconic IPs have also moved to this platform.

Among these first-party games, Xbox’s three exclusive pillar series – “Halo”, “Forza Motorsport” and “Gears of War” – will all be available on the Sony PS5 platform.

With the official announcement of "Halo: Campaign Evolved" landing on Sony PS5, this marks the first time the series has landed on the Sony PlayStation platform in 24 years.

A few months ago, Xbox also released "Gears of War: Reloaded" on the PS5 platform, bringing enhanced graphics and gameplay. This is also the first time that the "Gears of War" series has landed on PS5.

Of course, among these three major series, the first one to launch on PS5 is "Forza Motorsport".Earlier this year, "Forza Horizon 5" officially debuted on the PS5 platform.

Since the trinity of "Halo", "Forza Motorsport", and "Gears of War" is the core symbol of the Xbox brand identity, this also marks the complete end of the Xbox exclusive era.

Earlier this week, Xbox president Sarah Bond declared exclusive games obsolete.Halo, Forza, and Gears of War are coming to PlayStation, further solidifying this core idea, but also becoming part of Sony's PlayStation lineup.

On the other hand, both Nintendo and Sony PlayStation are advancing the development of multiple exclusive games.Nintendo is still sticking to its traditional strategy, while PlayStation has yet to port games such as Demon's Souls and Gran Turismo 7 to the PC platform.
