i often see the "ooga booga number go up" line-of-thinking used as a criticism against idle/incremental games, being that they often have the same sense of purposeless existence, apart from players garnering artificial and addictive stimulation. i have never seen that line-of-thinking be used for tower stacking, though. i like the bleakness and emptiness of the game, and while i question its effectiveness as a metaphor on capitalism, i like its uniqueness.
