Well...welcome aboard, lol. For starters, how'd you come about this website? And what aspects of Bully did you really "fall in love with", for the lack of better terms?
Well, to answer your questions:
1) I came across this site when I saw mention of it on the Canis Canem Edit tag on Tumblr. So I figured I'd check it out.
2) As for the aspets of the game I fell in love with, there is not just one or two. The whole game in general is great. Though I do like the class minigames, and the division of people into cliques. Those two aspects really give it the feel of actually being in school, rather than it just being, 'Oh, hey, the game's set in a school. Just throwing that out there.' And I mean those aren't the oly things that do that. Addition of getting busted for skipping class, and being out of dresscode are really nice to add to that.
