Regardless if they are art or not, video games still follow established rules. There's design philosophies that are used that have been tested time and time again because they work (unlke the crap Todd Howard thinks work). Games like Fallout 3 fail in too many aspects to be consider good in any capacity. So people can't throw around platitudes or just say "i had fun" as a measure of quality. There are games that i don't care about that i still appreciate for how well they are designed.
