When I read a count down, I've always preferred it when they count down O.o having the 1st placed item at the top ruins the list imo.
Technically, I am counting down but at the end it will look like I counted up perhaps. I guess it is all about presentation but I prefer to look at the top 10 right away with decent text about each game usually if I see lists in magazines. It all comes down to personal preference. I am too lazy to even type any description about them in the thread we post them.
