"The story is rather unrelated to the other entries in the Paper Mario series, plot-wise, though it has similar elements. It is notably a little darker, ever so slightly, than the other Paper Mario games, though it still blatantly retains, thankfully, many light-hearted, humorous elements. The overall plot is a little childish and somewhat expected, but pretty decent overall. It is noteworthy that many of these good characteristics seem to drop off about halfway through the game, but it is still okay."

If a comma represents where the orator must stop to take a breath, I can only assume they're doing a lot of heavy breathing to keep from laughing at the audacity of this sentence.
