During 1, the devlopment is aimed at the console.

Between 1 and 2, there is LOTS of optimistion specificaly aimed at the 
xbox. Also, the console resolution is usualy somewhat low. When the xbox 
was new, it was mostly connected to normal resolution TV sets...

When going to 3, the user wants greatly beter graphics. You want 32 bits 
colours, at least 1600x1200 resolution, over 30 fps, greater vewing 
distances, perfect anti aliasing,...
