those links don't work...Well really they do the same thing. There are some differences, of course. They have a different site ( e-tamago for entama and uratamatown for uratama), the uratama has
blue pixels and the entama has black. Different characters, games and the like.
Personally I like uratama better but you choose.
EDIT: Here's e-tamago and here's uratamatown
