Nintendo has given insight into its priorities when growing the Switch's install base as the console approaches the 100 million mark.
In its most recent financial results, the platform holder revealed Switch has sold just shy of 80 million units -- just 21 million short of the Wii, the company's best-selling home console to date.
In a conference call that followed, Nintendo president Shuntaro Furukawa answered questions on how firm plans to close this gap, indicating that selling multiple units to each household remains a key goal.
According to Nintendo's own research, 20% of Switches sold throughout October to December in key markets was "due to demand for multiple systems within the same family."
"We will aim to continuing increasing our sales volume by rigorously responding to this kind of demand for multiple systems," said Furukawa.
The Switch's back catalogue of million-selling titles will also continue to be key in growing Switch, with Nintendo revealing that 80% of games sold in major regions from April to December 2020 were ones released in the previous financial year, or earlier.
That includes Animal Crossing: New Horizons, of course, which released in March -- the tail end of the fiscal year. However, even without this title, back catalogue games accounted for 60% of Nintendo's software sales in the first nine months of its current financial year.
Key examples cited included Mario Kart 8 Deluxe, Super Smash Bros Ultimate, Zelda: Breath of the Wild and Super Mario Party. Furukawa also noted a boost in sales of Mario games around the holidays thanks to the Super Mario Bros 35th Anniversary campaign.
