Car collecting in
Forza 4 is actually how I became a fan of real racing in the first place. The better I became at the racing, the more cars I could buy and modify, so I worked on that and the more I learned about it, the more it became something other than just a means to an end
I watched all 24 hours of Le Mans this year and now record every sports car race (and F1) on SPEED and it's just starting to let me appreciate and understand the sport. I love multiclass racing and all that goes with it. Never gave it a 2nd thought until F4 hooked me a few months ago. I have played every version and never got it, always trading it in after a few weeks did the same with F4 and then picked it up again one day just for the hell of it and something CLICKED. I was like oh shit I need to turn this off and do some actual work... went weeks being sleep deprived. ha!
oh and I now have a used corvette on my "to buy" list to go with my F-150 so I can at least pretend I know what it feels like in real life.
