I agree... Forza 3 is a perfect case IMO if they included a SteelBook game case inside it would IMO be a perfect game release.
The region 1 release of MGS4 was very similar too...

I personally don't mind the big cases, but that's mostly because I picked up a huge shelf from Ikea and can display all my big box games on it...
if you have an ikea near you the shelf was called "LACK" and it was only like $60 fits everything but my NBA 2K10 box.
