@saifarabies Throughout the history of NFS there was few interesting name changing
NFS Most Wanted 2005 was originally NFS Hot Pursuit 3 2004
NFS Carbon 2006 was originally NFS Repo Man/Underground 3 2005
NFS Undercover 2008 was originally NFS The Chase and Most Wanted 2
NFS Most Wanted 2012 was originally NFS Most Wanted 2-2014
NFS 2015 was originally NFS Underground 3 2015
So clearly Carbon was the new NFSU(UG) and the online-only NFS2015 was also current gen NFSU(UG)
