I disagree strongly with you about games. Educational games do usually suck, but 'art games', 'indie games' and/or 'message games' can be really cool. Braid rocked not because of its weird metaphorical tell-don't-show 'story', but because of its well-executed and novel puzzles, beautiful art, and the final level which had more story in its wordless execution than the entire rest of the game.
