So, we all have those topics where, when prompted, we'll special fellow out and go into wayyyy too much detail on. What are yours? My two things that I'll special fellow out on if conversation steers that way:
-Electronic music genres. I get super micro-specific about these things. "No, that's not future house, it's post-2007 Romanian deep tech house!"
-NES memory mappers. For some reason I can tell people, when they talk about various NES games, what memory mapper chip they used. Castlevania 3 you say? That's an MMC5. StarTropics? One of the only games to use the MMC6, which was an MMC3 with an extra battery backup. Punch Out? Only game to use the MMC2. VRC7? Hell yeah I just bought the Lagrange Point soundtrack on vinyl!
