Sony and Nintendo battled it out - Horizon: Zero Dawn vs. Zelda: Breath of the Wild - but there was only ever going to be one winner when it came to sales.
Despite Switch's solid launch, Horizon: Zero Dawn was always odds-on favourite to win this week's chart rundown simply because of the huge number of PlayStation 4 consoles already in people's homes.
But the amount Horizon sold? It did very well indeed.
Horizon is Sony's biggest new franchise launch on PS4 - a title previously held by No Man's Sky. It's also the biggest PS4 launch in general since Uncharted 4.
Below Horizon in the chart, Zelda: Breath of the Wild was second. 78 per cent of copies sold were on Switch, with 22 per cent on Wii U - the latter figure perhaps higher than expected.
Grand Theft Auto 5 was third, ahead of Switch launch title 1-2 Switch.
For Honor was fifth, FIFA 17 sixth, followed by another Switch launch game - Super Bomberman R - in seventh.
Rocket League, Sniper Elite 4 and Battlefield 1 filled out the rest of the top 10.
