I live in Australia and I'm used to maint during MY prime time whenever I play an MMO so here I'll give you a couple of examples of what people can do when maintenance is during prime time
~Read a book.
~Watch TV.
~Go out for dinner with family/partners/friends.
~Go see a movie at the local cinemas with family/partners/friends.
~Play other video games be it on a console or online.
~Go out to the local bar and get hammered (If you're of legal drinking age in your country or if you're one of those tricky people with a fake ID).
~Spend time with your family and friends.
~Have an earlier night so you're well rested for the following day.
~Make it a study night (for people who attend high school or university).
~Exercise (gyms are open at night till around 9/10pm some even longer).

Now remember! Life is there to live even if the graphics are a little bad compared to FFXIV....
