Better question: whats the difference between core and hardcore gamers?
Anyway, casuals play games primarily to bond with tohers, and don't bother to learn alot of facts/become particularly skilled. They like Guitar hero, Wii sports, Monkey ball, mario, Imagine, Nintendogs, Mario Kart, Smash Bros, Animal Crossing ect.
Hardcore gamers don't want the industry to change, expect to be catered to, like overly violent/overly sexual games, care alot about technological capabilities, are very well informed about video games, are very skilled at gaming, and are generally very competitive gamers who like playing online.
I consdier myself a core gamer, as I don't expect to be catered to, don't like voilent or sexaul games, don't care very much about technological advantages past the GC (I don't like DS's 3D though), am very well informed about gaming, and am only mildly competivitve and dislike playing online.
