It's amazing how Nintendo does the opposite of most people.
You see a trailer or screenshot at E3? Chances are the final game won't look THAT good. (Colonial Marines, Killzone 2, Uncharted 3)
When you see a trailer or screenshot for a Nintendo first-party at E3? Chances are the final game won't look THAT bad.
Others have bullshots.
Nintendo has crapshots.
(I'm not saying that EVERYONE that isn't Nintendo does this, but some do.)
not only do they make their shown footage look better, but they rarely even show off the best looking stages. they keep those as surprises. it really is something else. it shows how different their game development strategy is to their competitors.
