The new ranking, shared alongside a report from Nintendo Life, highlights the continuing commercial impact of console transitions and high-profile single-player releases.
GfK's weekly UK chart places Marvel's Wolverine at No.1 for its debut week, with Nintendo's Fire Emblem: Fortune's Weave entering at No.2.
LEGO Batman: Legacy of the Dark Knight climbed back into the top three, driven primarily by sales on Nintendo's newly released Switch 2 hardware: GfK's platform split shows LEGO Batman at 87% Switch 2, 10% PlayStation 5 and 3% Xbox Series X|S.
Rewriting key observations in clear, journalistic language: Nintendo Life noted that both Nintendo and Sony had high-profile releases during the tracking week, and GfK's chart confirms that Marvel's Wolverine took the top commercial slot on debut while Nintendo's Fire Emblem title maintained a strong second-place showing.
The Switch 2's launch week share is visible in the chart, with several entries showing significant Switch 2 percentages.
Other notable placements from the GfK top 40 include long-running sellers and catalog titles performing strongly alongside new releases.
Multi-platform titles show varied platform splits: Onimusha: Way of the Sword recorded 83% PlayStation 5 sales, 10% Xbox Series X|S and 7% Switch 2, while EA Sports FC 26's breakdown was more evenly distributed—30% Nintendo Switch, 28% PS5, 17% Switch 2 and 14% PS4.
Legacy and catalogue titles such as The Witcher III, Grand Theft Auto V and Minecraft remained in the upper tiers of the chart.
The GfK compilation offers a snapshot of the UK market during a transition period for Nintendo hardware, with the Switch 2 already accounting for meaningful shares of multi-platform sales in its opening weeks.
For developers and publishers monitoring platform migration and consumer purchasing, the chart underscores how new hardware can re-energize back catalog sales and affect multi-platform performance.
