It's not just something specific to one game as far as realistic features go. My job takes me to several NASCAR races a year and I know for a fact that many of the drivers and team members are huge racing gamers. Especially the games that offer great representations of specific tracks. Several drivers in both NASCAR and ARCA use the simulations to practice hitting their points on tracks that they don't have much seat time on or do poorly on. If a professional driver like Dale Jr. like racing games then who am I too dislike them!
