Steam Release Overview

The arrival of the Kingdom Hearts Final Mix collection on Steam marks a significant shift for PC gamers. Previously tethered to the Epic Games Store, the series now embraces the Steam ecosystem, bringing with it full support for the Steam Deck. This release includes not just the original Kingdom Hearts Final Mix, but the entire "Kingdom Hearts HD 1.5 + 2.5 Remix" collection, "Kingdom Hearts HD 2.8 Final Chapter Prologue," and "Kingdom Hearts III" with its Re Mind DLC.

Video Highlights:

  • Collection Scope: Includes KH Final Mix, Re:CoM, 358/2 Days, KH2 Final Mix, BbS, Re:coded, DDD, 0.2, Back Cover, and KH3 + Re Mind.
  • Pricing Strategy: The full bundle costs around $100, but individual games are available separately.
  • Steam Deck Focus: The video highlights the Deck as the primary reason to choose this version over Epic.
  • Performance Analysis: Discussion on frame rates and graphical settings for handheld play.

This port is largely identical to previous console and Epic versions, utilizing AI upscaling to improve background textures. While the core gameplay remains untouched, the convenience of Steam Cloud saves and Deck verification adds significant value for collectors and new players alike.

Price Consideration

The full collection is priced at approximately $100. While this provides hundreds of hours of content, many of these titles are older classics. Consider if you already own them on other platforms before committing to the full price.

Performance Analysis & Graphics

The technical performance of Kingdom Hearts Final Mix on Steam is robust, though it does not reinvent the wheel. The ports are described as "simple and clean," functioning well on standard PC hardware.

FeatureStatusDetails
Frame RateStableRuns smoothly at 60fps on modern hardware.
TexturesAI UpscaledBackgrounds are sharper but can look inconsistent.
SettingsBasicLimited options, mostly framerate and quality presets.
Steam DeckVerifiedRuns well; KH3 requires settings adjustments.

The most notable technical addition is the AI upscaling applied to background elements. This technique sharpens the environment, making pre-rendered backgrounds look less blurry on high-resolution displays. However, as noted in reviews, the AI sometimes produces artifacts or "strange" textures where the algorithm misinterpreted the original art. It is a subtle improvement that enhances clarity without drastically altering the game's aesthetic.

Visual Settings

If you are playing on a high-end PC, do not expect extensive graphical tuning options. The settings menu is streamlined, focusing on "Overall Quality" and frame rate caps rather than granular texture or shadow controls.

Steam Deck Optimization

For many, the Steam Deck is the definitive way to experience these classics. The entire collection is verified, meaning it runs out of the box with minimal tweaking.

Performance Breakdown:

Game TitleDeck PerformanceNotes
KH Final Mix / IIExcellentRuns like a native PC port; handheld friendly.
Re:Chain of MemoriesExcellentStable performance throughout.
Birth by SleepExcellentFull 60fps experience on the go.
Kingdom Hearts IIIGoodRequires lowering settings for stable fps.

While the older titles (KH1, KH2, BbS) run flawlessly, Kingdom Hearts III demands more from the hardware. To maintain a steady frame rate on the Deck, you may need to lower shadow quality or disable heavy effects. However, even with these sacrifices, it remains a highly playable portable experience.

1

Verify Installation

Ensure the game is fully updated via Steam. The Deck will automatically apply the correct Proton compatibility layer.

2

Graphics Settings

For Kingdom Hearts III, navigate to the display settings and set the overall quality to "Standard" or "Low" to ensure smooth gameplay during combat-heavy scenes.

3

Controls

The Deck controls map perfectly to the original layout. You may customize the back paddles for camera control if you prefer not to use the right stick.

Content Breakdown & Value

The Steam release offers flexibility in purchasing. You can buy the massive "Kingdom Hearts All-in-One Package" or split the collection into three distinct bundles.

Story So Far Bundle

  • Includes: KH Final Mix, Re:CoM, 358/2, KH2 FM, BbS, Re:coded.

Missing Title

Notably, Kingdom Hearts: Melody of Memory is currently missing from the Steam lineup. This rhythm game would be an excellent fit for the Steam Deck, but it is not available for purchase as of this review.

Final Verdict & Recommendations
