I dunno yet. If there's a NIB game that's awesome then I'd like to try something new. But I'm not excited about anything prematurely. Sure, Ghostbusters is happening. But that doesn't mean it's a great game, it just means it's being made. Merely existing isn't enough to get my heart racing.
So when it comes to non-NIB games you kinda just have to see what falls in your lap. I think I'm nearly done with exploring classic Bally SS games, but I haven't owned a Centaur yet, and I'd kind of like to if I can do it for something that's not $4000. Not worth it at that price.
But mostly I think it's about seeing what's out there. I'm past the point of listing 5 games, more like I have cash, what shows up?
