Hrmm...I'm okay with the Bukkit loss, but if the old maps could be up for download, that would be nice to reminisce in SSP. I suppose I'm fine with either direction, but FTB from what I've played with goes way beyond Tekkit. I want me a giant pine forest.
And I mean the super-huge mega pines!
The one I've seen the most of is the direwolf20 pack, but I've watched a bit on the others, too. I haven't seen any LP really dive in and get far enough to showcase the differences between them yet.
