This would especially help people who wish to play the less-popular games, where you are having difficulty enlisting a group to play. I guess it's sort of obvious how this would work - set up your table as normal, but provide a specific start-time. Players would join at their leisure, and be ready for the real-time start. This would also give them a chance to review the rules before the game starts.
Again, this is suggestion not for turn-based games.
