Absolutely nothing. I've wrestled with the idea that maybe I'm done retro collecting now. For a long time I've felt so close, yet so far away. Several hundred games on my list I still wanted to get, but it's meant several thousand dollars I'm just not willing (and don't have) to dump into it. Hard to believe this stuff is still going so strong all these years later, folks clamoring to collect every title you can think of, for every console you can think of in 2025. I know the appeal of doing so has greatly diminished for me. I think it's mostly the speculators still going this hard at it.
I actually found myself in my local retro shop the other day and actually picked up a couple of NES games on the cheap, unexpectedly. So guess I'm not done. I just don't have the motivation to pursue it anymore. I'm really close with a lot of fifth gen stuff, so if anything I should try knock those out. Still a lot easier said than done.
