Most people don't finish videogames?

To be honest I find that sort of a let down. Developers put so much effort into making the games be complete when 80 percent of people don't even get there. I don't know about you guys but I beat every game I ever had even shrek for gamecube which was a decent game. Only game I never beat was when I was a kid playing the N64, there was a bowling game on it that I never got myself to beat only keep replaying the same levels but Im pretty sure that was because you couldn't save.
