GB is the only NIB I have ever sold as well. I still own AS and ST both of which are the LE flavor. But to be honest my SW might be the second NIB that gets sold. (Its fun but I find that I just flip at the ball non stop and really don’t know what the hell im doing!! Lol)
Of all my pins I find I still play TWD and MET the most followed by IM:ve.
I will admit though, I am a simple player. Not one that likes a “deep” game.
So of your choices, I would say AS, but if you can consider TWD, I still have a blast playing that machine.
Good luck!!
