Wish I had seen this thread sooner. I'd say the value of these is very dependent on how popular and well-loved the subject matter is. Anything related to Might No. 9 is reviled and worthless except to maybe the handful of people that like to collect stuff related to massively disliked franchises. Modern Star Wars Battlefront is similar, though not as bad. On the other end of the spectrum, Nier, Fallout, and Dark Souls are very well liked and therefore desirable.
Keep me in mind if you decide to sell the Mighty No 9 and either of the Nintendo signage.
