To be honest, this is my pink dream, but we need to face reality: 25 games per player is too many, not because it's a lot, but because there will be dodgers and throwers, and balancing the matchups based on results will be extremely difficult. So for now, we'll stick to two groups; currently it looks like 13 people per group. By the way, 8 people from each group will advance to the final stage, so most of those who want to and have time to play will have a chance to fight in the finals as well)
As for the second part of my proposal, I consider it quite viable—limiting it to something like 1 game per week is too strict, but 3 games per month is, IMHO, quite realistic; during that time you can go on vacation, go on a business trip, and still manage to play if you want ;) And I think no one doubts that limits are necessary—previous tournaments both here and on other resources have long made that clear
