The Nintendo Switch 2 has made a strong entrance into the gaming market, with 3.5 million units sold since its release. While many players are diving into *Mario Kart World*, the question remains: how much are users investing in other titles, especially those not developed by Nintendo?

Early sales data offers a nuanced look at the console’s software performance during launch week. As expected, Nintendo’s first-party titles continue to dominate their own platform. Approximately 80% of Switch 2 consoles sold were the bundled version that includes *Mario Kart World*, setting a high bar for third-party visibility from day one.

The Switch 2 launched with a mix of new offerings, including the interactive tech demo *Nintendo Switch 2: Welcome Tour*, enhanced editions of *The Legend of Zelda: Breath of the Wild* and *Tears of the Kingdom*, and full backward compatibility with the original Switch library. These compelling first-party options, combined with the bundled game, naturally shift consumer focus away from third-party releases.

In the UK, first-party Nintendo titles accounted for 86% of physical game sales during launch week, according to NielsenIQ data reported by The Game Business. This closely mirrors the 89% first-party share seen during the original Switch’s debut week. The US market showed a slightly more balanced trend, with first-party titles making up 62% of physical sales, as reported by Circana. Notably, this is a significant improvement compared to the original Switch’s first month, where first-party sales exceeded 80%.

Despite the dominance of Nintendo’s lineup, some third-party titles managed to break through. *Cyberpunk 2077* by CD Projekt Red emerged as the top-selling non-Nintendo game during the Switch 2’s first week. Sega also had a strong showing, launching *Yakuza 0: Director's Cut*, *Sonic x Shadow Generations*, and *Puyo Puyo Tetris 2S*, securing its position as the third-largest publisher on the platform during launch week.

However, not all third-party publishers are celebrating. According to The Game Business, one unnamed developer described their Switch 2 launch sales as “below our lowest estimates,” highlighting the challenges of gaining traction alongside a Nintendo giant. With no pre-launch reviews available for third-party games and *Mario Kart World* leading the charge, limited visibility may be a contributing factor.

Another key difference from the original Switch launch is the broader software selection. While the first Switch launched with only five physical games, the Switch 2 entered the market with 13 available titles, potentially dispersing consumer spending across more options.

As industry analyst Mat Piscatella noted, it’s still far too early to draw definitive conclusions about the Switch 2’s impact on third-party publishers. “It’s far too early to claim best or worst this or that or whatever when it comes to Switch 2,” Piscatella stated. “Sheesh, the thing hasn't even been out 3 weeks yet.”

While the data provides early insights, long-term trends for third-party success on the Switch 2 will become clearer in the coming months. For now, the platform’s hardware momentum is undeniable — and with time, broader software adoption may follow.
