Midgar was my favorite part of FF7 too. I still think more could have been done with it, though.
As for the naughty screens, it's the kind of stuff I expect from the likes of Compile Heart or Idea Factory. Humorous "bromide" type screens peppered throughout the game that sometimes border on creepy. For all we know, the vines could be part of a tickle plant encountered somewhere in the game and the artists decided to make a visual "c wot i did thar?"
Would I still try out an English language version of Tokitowa? Sure, why not?
