I recently added Lockdown to my collection on top of the original Nemesis. They’re both absolutely amazing story generators. The second one is a bit more optimized for learning, teaching, and playing. I would strongly recommend Lockdown over the original. Not because it is way better, it just has several desirable improvements, but because if picking one over the other, those refinements are things you don’t want to choose to play without.
Just putting this out here, you do NOT need to use the joy/pad for mouse and it works great. Such a fun game. Great for the deck.
