Star Wars Outlaws developer explains that Nintendo Switch 2 game cards are too slow for a physical game release — Snowdrop game engine uses disk data streaming to render the game world
Game built to target faster SSD platforms would need too much rework for slower cartridge-based storage.

Ubisoft wasn’t being ‘cheap’ by opting to deliver Star Wars Outlaws for Nintendo Switch 2 via Game-Key Card, according to a developer who worked on the title. In a discussion thread on BlueSky, Rob Bantin, Snowdrop’s Audio Architect, explained that “Switch 2 cards simply didn’t give the performance we needed” to run the game at an acceptable quality. The Snowdrop engine uses a lot of disk data streaming to render open world environments.
The Switch Game (Key) Cards mess
If you aren’t very familiar with the Switch 2, there’s an important distinction to be made before discussing the issue here. Nintendo facilitates Switch 2 games distribution digitally online (simple enough), and on physical media dubbed Game Cards (even simpler). However, there’s a somewhat controversial third way: the Game Key Card, which acts like a kind of dongle signaling ownership of a title and allowing you to download and play it on the console that you insert it into. After installation, this kind of game does not required constant internet connectivity, but you'll keep the card in the slot to fire it up.
Switch 2 Format | Description | Internet required? | Performance and portability | Used resale? |
Digital Download | Purchased via eShop; the game is tied to your Nintendo account | Yes (to download) | 2,100 MB/s data rate, but locked to your account | No |
Game Card | A traditional cartridge with the full game data onboard | No | 400 MB/s data rate (eMMC), Plug-and-play; no download needed | Yes |
Game Key Card | A physical cartridge containing a license key, not the game | Yes (first time) | 2,100 MB/s data rate, uses built-in storage, but card must stay inserted to play | Yes |
Game Key Cards are widely acknowledged to be cheaper to make for the games publishers. No flash required. And the gaming community is naturally resistant to dongles, DRM, and what has here been referred to as the worst of both worlds. Moreover, Nintendo’s Switch 2 comes with a measly 256GB of internal storage.
Expanding your built-in storage with MicroSD Express cards adds a middling third performance tier of ~800 MB/s transfers to the machine. These cards, sold in sizes up to 2TB, are quite costly for users, as we have highlighted previously. However, if the physical Game Cards matched this performance spec, perhaps we wouldn’t see games like Star Wars Outlaws being forcibly shoveled onto the limited built-in storage of the Switch 2 via Game Key Card distribution.
Cost of cards was “moot”
Moving back, now, to Bantin’s reasoned defense of the use of Game Key Card distribution for Star Wars Outlaws, and the dev underlines that “I don’t recall the cost of the cards ever entering the discussion - probably because it was moot.”
Game design makes a difference
The Snowdrop’s Audio Architect would later share some further insight into the situation regarding Game Key Cards and Star Wars Outlaws. He reasoned that developing for platforms with faster storage standards first meant compromises when it came to the Switch 2 version's distribution. “I think if we’d designed a game for Switch 2 from the ground up it might have been different,” Bantin said. “As it was, we’d build a game around the SSDs of the initial target platforms, and then the Switch 2 came along a while later. In this case I think our leadership made the right call.”

bigdragon I'd rather install the game via game card than download the entire thing from the internet. Modern games are huge. Not everyone lives in an area with fast internet. Having the game on the card also means I can go back and play it in the future when the servers go down.Reply
I really don't understand the hype for the Switch 2. It doesn't have enough onboard memory. Game key cards are the most annoying parts of physical and digital media combined. Many of the Switch 2's games are ports from other platforms that deliver a better experience. -
edzieba Doesn't pass the smell test: if R/W speed was the only reason, then shipping the same installer that you would download as a file stored on the card, and then installing it anyway before play, would solve the problem, and allow for offline play.Reply
The reason was wanting to sell cheaper cards for the same RRP. -

Low quality ports, the mortal kombat port was beyond funny, didn't think you could lower the quality that far down.bigdragon said:Many of the Switch 2's games are ports from other platforms that deliver a better experience.
Perhaps Nintendo should stop asking dev's to port their triple a titles to something that's as powerful as a smartphone. This is a handheld not a ps5 competitor. -

Cyberpunk and Street Fighter 6 show that it's definitely possible to get good ports on the Switch 2 (similar hardware than the PS4 by the way). And people have pretty good words about the Mortal Kombat 1 version on Swicth 2. They say it runs way better and looks much better. One comment I found says that it's so much better that it made them realize how bad the original Switch port was.S58_is_the_goat said:Low quality ports, the mortal kombat port was beyond funny, didn't think you could lower the quality that far down.
