Jenny was probably the biggest route since she has the most content, right? I remember you saying ages ago that they were saving the big ones for last, but I don't know if we've ever gotten a strict accounting of what routes have actually been completed (or at least as completed as they'll get at whatever phase of development they're in, anyways).
Do you know what ones they have left to do? If memory serves I know I've seen discussion of Eve, Jenny, Diane, Debbie, and the Main Stories being worked on at various points. Roxxy has to be a big one with all the stupid little minigames woven through her route and her varying interactions with both Eve and Jenny.
