Nope, I pre-order from Best Buy because if you have a My Best Buy account, many of the major titles (not from Nintendo) come with a $10 rewards certificate. So, 15 days after you pick up your pre-order, you'll have $10 off your next game. Given GCU's discounts, I'm then buying a game for $52 (after tax), and if it's finished quickly, it'll trade in for $44, then I'll get $10 in rewards towards my next game. So, I'm making $2 on games when I pre-order. Such was the case for Sunset Overdrive, Advanced Warfare, The Master Chief Collection, Dying Light, and maybe another game or two.
On the plus side, the issue of Forza 5 is fixed with Forza 6, as the content is upped to 450 cars and 27 tracks (from 200 and 17). Basically, Forza 6's announcement was Turn 10's statement that Microsoft screwed them into releasing half of a game because the Xbox One needed it at launch, and they were still working with new tools and didn't have time to finish the game. So, while CARS is technically broken, Forza wasn't, so I'm not concerned this time.
