Wait, hang on! The game is timeless and deep down inside I know Street Fighter is the greatest series of fighting games of all time, even though there are so many great other series, there is! The point could be argued all day long. The thing is this, as amazing as the game is, I thing that the sprite work on the stages is flawless, I mean the renditions of these places on pixel art level is ridiculous, the sprites of the characters is also amazing, pixel art is very difficult to work with if you want detail, the artist is always hungry for more pixel count in order to make a more detailed sprite. So with that challenge in mind, yes SFII is a masterpiece and so are many games of that era and we're just talking graphically here.
The mechanics are still used to this day, enough said about that, simply amazing! Here's the big but, would you consider the gameplay art?
The real point is thin though, art can only be impartially judge from the source, and the concept art for some of the renditions wasn't as breathtaking as you would call, oh man that's ridiculous or anything. It's good, it does the job and it takes you there, but tons of video games can be catalogued in that same category. Work of art in the merit of the word as a sentiment, yes, but this is not exactly the same, I mean I think art, I think a painting, an opera, a play, something that's virtuoso like, something artistic like. In sense some of the partakers of the game are artist, of course, it's part of it, but not all of it. At less you want to call a person like Einstein an artist, am I wrong?
