The Last Guardian's market performance might be under the most scrutiny of any other game this season. The game took almost ten years to develop, and reviewers and fans were hotly debating whether The Last Guardian would be an enjoyable experience or a spectacular failure in the days leading up to release.
Reviews have lauded the game, and the numbers show that consumers are as well. In the UK market, Team Ico's latest project managed to place #7 in the Top Ten sales for last week.
The Last Guardian outsold Team Ico's last project, Shadow of the Colossus, if you compare their first week sales. Seeing as Shadow of the Colossus was in the #1 spot during the week of its release, it's evident that industry sales as a whole have grown tremendously in the last decade.

That should cover 10 years of development.
