This time, there're no strange businesses. It's all the regular stuff, just expanded almost to the point of exploding. Well done!
There are some contents that would only make sense to enthusiasts. For example, one of the questions to Yuki is, "I got assigned the same spot as Kyon's seat at school, but Haruhi is not behind me. What do I do?" And her answer is, "Go to Kouyouen gakuin to find her." That would make absolutely no sense unless you read "Suzumiya Haruhi no Soushitsu." There are other stuff like that too. But then, if you're buying this, you're most likely an enthusiast anyway, right?
And the original jingle III is horrible! That isn't to say that it's bad. Or rather, it's so bad, it's great!
And don't stop playing when you think it's over. Wait a bit and the last track has more stuff in it. This part also won't make sense to non-enthusiasts (people who didn't read Suzumiya Haruhi no Bousou), though.
