This is going to be something that varies from person-to-person. I stopped going to FNM regularly because I and most of my friends started working full time 9-5s, and we stopped being able to go out on a random Tuesday Night, so Fridays and Saturday nights were reserved for going out and being with people, and not in a Card store till 10:30 PM. Now, when I play, it's in the Saturday afternoon event, which gives me the morning to do housework, and the whole night to do something else.
who knows friday is much more convenient than on the weekends imo.
When I was in high school, I had a part time job that was noon to 6 on Saturday, so going to Friday Night Magic was actually something that worked for me and was something that I looked forward to.
