GT Sport has gone to the top of the UK charts, apparently selling 3x more physical copies than Forza 7 - No actual numbers given.
"Data from Chart-Track reveals Gran Turismo Sport, the first in Sony's long-running racing sim series to launch on PlayStation 4, had better week one unit sales than both the original Gran Turismo, which launched on PS1 back in 1998, and the last version, Gran Turismo 6, which launched on PS3 back in 2013."

Interesting to see GT still sell well, even with some of the controversy around it. Owning the game myself though, I can say it's really good, if you can get past the big changes.
