I don't see how people have, for centuries, spent their lives doing pointless things like playing sports, playing random games/puzzles, going after women for the thrill of it, etc, and none of them are deemed to be the same kind of loser that a no-lifer is. Once you really think about it, there's nothing that will really have any significance in life. 99% of the time, nobody will even mention your name 10 years after you die, except for your family and close friends who outlive you, so why not make life as enjoyable as possible doing what YOU want to do?
