To me, it's nothing. (Not to sound like a troll but continue reading)
I don't own a 360 as I find it's value doesn't justify a purchase. However, I enjoy their Halo games which is why I own all the Halo games. I buy their games but I just borrow a 360 from friends and family.
This is something I'm doing currently for 360 & Wii U, (and possibly Xbone), where I'll like some of their games but not enough to purchase the system. So in the mean time I'll purchase the game and find the system to borrow. As well, I purchase games that I know will be harder to find down the road so at least i'll have the game because you can always get your hands on a console but not always for the games. I'll wait for the 360 and Wii U to go down to $99.
I guess if I were to give an answer for this thread, then it'd be Halo.
