Tomb Raider (1996 video game)
The front of the Derby Studios building where Core Design worked on the game was later used as the front of Croft Manor. It is Core's contention that the company was struggling somewhat with 32-bit development at that time. The first glints of the game were seen on Sega Saturn development kits. However, Gard stated that though Core and Sega had a deal for "Tomb Raider" to be a timed exclusive for the Saturn, the game was developed simultaneously for the Sega Saturn and the Sony PlayStation. Following the release of the Saturn version, a number of bugs were discovered that affected both versions of the game; because of the timed exclusivity, the development team fixed these bugs for the PlayStation version. While the series would see four more instalments on the original PlayStation, no additional "Tomb Raider" games were released for the Saturn. Additional Sega ports were released on the Dreamcast.
Rise of the Tomb Raider
Some gaming journalists were concerned about "Rise of the Tomb Raider" sales, since it was released on the same day as "Fallout 4" (a highly-anticipated game from Bethesda Game Studios, which also had Microsoft as its marketing partner). However, Microsoft believed that the games would not compete with one another. It was the fourth-bestselling game in the UK and Ireland in its week of release, debuting at number four in the UK retail software sales chart (behind "Fallout 4", "" and "FIFA 16"). However, the game did not sell well enough in the month after its release to appear on the NPD Group chart. According to Square Enix, its initial commercial performance was "solid"; game director Brian Horton and Microsoft executive Aaron Greenberg said that Microsoft Studios and Square Enix were satisfied with the game's sales. Digitally, the Windows version sold three times better than the Xbox One version in the first month of release. The game had sold over one million copies by the end of 2015, 
and nearly seven million copies by November 2017.
