[pygame] Using sprites versus simple surfaces

[Farai Aschwanden <fash@xxxxxxxxxx>]

Hi all

General question about using sprites in Pygame: Whats the big thing  
of sprites in Pygame? To be honest I didnt use Pygame's sprite  
functions yet, but except creating groups I dont see many more great  
features to make my programming life easier than just using surfaces.  
If sprites move are around I also have to care about the background  
refresh, as far as I understand the functions. A simple collision  
detection can also be done by checking overlapping rectangles. So  
whats the big thing of using sprites?
