I'm planning on recording a Fallout 4 playthrough for YouTube today actually! It's a permadeath, no healing run and I'm super excited to check it out. I was originally going to try it with New Vegas but compared to Fallout 4 my NV knowledge is really lacking and after the recording I TRIED to do for NV was really badly audio balanced I figured that was a sign I should go back to 4.
4 is definitely my favorite out of all the games, but surprisingly I seem to be one of the few people who actually enjoys Fallout: Tactics. Don't get me wrong, I like New Vegas (I always joke that one day I'm gonna marry Benny), but I feel way more drawn to everything the Commonwealth has to offer me
Also MacCready has the same voice actor as one of my other all-time favorite video game characters and the voices are so similar in my head that it always makes me super happy to hear him talk even if I don't take him out of Sanctuary very much.
