I met the CEO of Club Penguin while at Web 2.0 Expo. He struck me as a very nice guy — and also very committed to the charitable, help-the-world, have-great-kids’-entertainment side of things.
As TechCrunch comments, that may be a bit of a stumbling block for Sony. I don’t know for sure, but I have heard that Club Penguin donates a large amount of their earnings. Sony certainly has a charitable heart, but they also don’t exist for that reason, whereas Club Penguin is founded on that sort of idealism.
