Of course (as I just wrote) I appreciate games as an art form (to the degree that some have good art. Most have bad art, just like in the art world proper). But playing games cannot be compared to the value of reading books (in general). That's absurd.
Im interested in the two parts of this statement. The first thing is you refer to games as an art form but then in brackets only refer to the "art". Are you referring to only art in this case or are you using the word art to refer to everything within a game? Your sentence sounds like the former but it would be quite bizarre if it was.
The second part then what value are you referring to. As entertainment, art form, learning, experience? There are a lot of arguments that could be made on both sides but it really depends what you mean.
