IRL coworkers - I don't bother talking about videogames with most of them, I think the only one we have in common is Skyrim.

Online friends - I swear to god I can't talk to half of you because all you guys ever play are JRPGs and that's one of my least-played genres.

Some of you have pretty good taste though (people who show up in my SMAC or Morrowind threads, I'm talking about you guys )
