Maybe tie in a Quest to Reconnect the old Rope travel system... 1 Zip line is working when you install the mod to wet your appetite. then you need to collect Mamouth Hair or something hard to kill, (about 10 to complete 1 single zip line).Maybe some other Mats also, idk So that would keep you busy a while,, there are no grinding type of quests in skyrim where you really look forward to finishing it, and it takes a while... Then maybe a time limit after you finish one, so you cannot use the console, cheat, or hook up all 5 in 2 minutes. 1 week waiting period or something. The suspense will kill you... (The best part of Wow was grinding until you get your mount) same idea. The Rope Crossbow seems like a great idea also, but who knows if modders can do that or the zip line... hymmmm
