I never said that the model would have only 8 or 80 polygons. And believe me when I say that collision detection would be faster for polygon-precise collisions.

In a game the collision detection is the most time consuming part that slows down the game. And where there are many polygons that are used, then the time to check for every polygon that might collide, is great.

I think that, instead of giving advantages, I should have only asked for this feature to be implemented. Because all the interpretations that have been done, are your own specific point of view and vague in nature and dont co-relate with what I am putting forward.

An example what this feature would help in, is people like small demo downloads and instant play startup.
