What kind of question is this? games are first and foremost, a means of entertainment! you don't find people mounting a copy of halflife two in a frame at the tate modern, admiring it's impressionist take on modern life! You find people sticking it in the dvd drive, shooting headcrabs and saving the world! ever since pong came out, people played video games to relax, or to vent frustration, and it sticks to this day.
Of course, in modern times you find that games have become so flawless in their design that people are under the illusion that it was forged for the sole purpose of pleasing the eye. where this may be the case for some ventures, It is hard to see the artistic side of gorefests such as gears of war and fallout, where wondeful visuals are put to use to show off the copious amount of arteries and vital organs below the epidermis... but i digress. My point is, if you hadn't realised by this point, that videogames are fun, otherwise, people wouldn't play them. but now for my next point: is it too much to ask for both?
