I preordered both of them. Played SC2 for about 4.5 hours straight after I got it on Wednesday night. Then next day found F-Zero at my doorstep after getting home from class. But then had to go to work,, aargghh. Anyways, i have been playing more fzero than sc2. That game is just so addicting, fast, sharp, and awesome. It is hard, very hard. But most of the times it is just little turns, boosts, or jumps that make all the difference. Took me about 25 tries to beat chapter 3 in story mode. A bit of acceleration vs top speed adjustment helps too.
