Video games have evolved so much to me considering the first I ever played was Atari, lol.
I love the Atari. Theorists say that video games are an art form.
Really?  Well, I get the artistic aspect of it.
The designation is controversial, but I do think some games are art.
You do have to be very creative to design the games.  
The games could be two- or three-dimensional images.
So true.  Computer graphics have become increasingly complex.  I know I wouldn't have an idea how to do it.
And they have lots of platforms ranging from large mainframe computers to small handheld computing devices.
