The one's I actually wanted but never got to purchase before I sold most of my collection were Ninja Masters, Sengoku 3, Metal Slug's, Kizuna Encounter, Blazing Star, Pulstar. I searched for these much later on since they weren't at the top of my list but by that time it was too late. I never paid over $1k for a game. I purchased most of them when they were in the $50-500 range. The most I paid was for MOTW and that was like $800 from Yaj.
Selling these games were a pain in the ass. Everyone outside of this forum assumes the games are fake from the jump. I sold most of them here for reasonable prices versus selling them outside the forum for more just to avoid the bullshit.
