Well, let's go through this one-by-one. We should avoid using kiddie-like words such as "creepy" in artices, I think. For the Collision Chaos entry, "dismal" would be a better word. I'm also not sure about descriptions such as "dreamlike and surreal". What is dreamlike and surreal about it? And what precisely is "rather odd" about the buildings in SSBF? To me, it simply looks as if they are very, very densely packed, probably because of overpopulation issues. I think we should also avoid giving levels too many concrete descriptions such as "factory" or "aquarium", because peoples' perception of the stages vary greatly. You may think that WW is a factory, but I have always seen it as a power generation plant. Likewise, to me, TTGF is a hydroponics facility, not an aquarium. Also, we shouldn't use "Eggman" and "Robotnik" in the same article, let alone the same paragraph. The official Wikipedia article is Doctor Eggman, so IMO, that is what we should use.
