Even if based on the assumption that you were working for AW, Bigfatchef's points are very valid. If GENCON tournament is meant to be the biggest and the greatest tournament (as we all assume), I think that the tournament should be defined and have concrete objectives. These should be defined by AW. I know, we are always asking more and more from this little company, but we just love the game so much that cannot do otherwise!
Based on the tournaments organized by other games and publishers that I have liked:
-Tournaments are part of a continuum. Normally organized with full involvement of the publisher. (assumption- for the case in point I understand there is limited involvement of AW).
-There is expectation created by announcements in the communities, new expansions coming out, the meta changes right on time just to make everybody doubt about what type of play can win, possibilities to get byes at regional tournaments (if possible), podcasts talking about it, interviews with the publisher talking about it on youtube, the prize pool is announced in full.
-Then, the tournament takes place. Normally the publisher plans it and estimates de number of seats they need and prepares for that. If someone signs in late, then there is a waiting list just in case. But the tournament is manageable because estimates are more or less accurate (if you practice, you can only get better at it!).
-After the tournament there is some media coverage by podcasters or youtubers, analysis, and fans replicate what the top 4 did (just for fun), and players know what to expect in terms of expansions and the next tournament the following year.
In a nutshell, I think that one can notice a big difference between those tournaments that count with full involvement of the publisher and those that do not. It would be great to have THE OFFICIAL tournament of MW at Gencon, or somewhere else (less expensive?).
At the end of the day, considering the time that the game takes, and the nature of our community (small but passionate), I cannot see an added value of organizing this at Gencon. Visibility is important, but there are many ways of achieving that.
And here is the main idea that I would like Silverclaw, Aaron and AW to think about:
If less money would go to rental of space at Gencon and more resources would go to create hype in the community and to PROMOTE the OFFICIAL tournament, it would be a good opportunity for fun and for business. There could be several alternatives and options to go around this. Of course, if you increase the level of resources for this tournament, you can always do it at gencon, but the promotion factor cannot be absent (as part of a continuum). With more promotion, I think the organizers (silverclaw, etc) would be able to do even a greater job.
I hope this helps.
