Thank you all for the kind comments... I'm currently debating possibilities for the future of this tournament type/franchise.
1: repeat, doubling the number of 5-player games. (60 games per round, 44 per player)
2: run the 5x5 grid, drop the 3 player games, double the 5 player games (30 games per round, 26 per player)
3: modify to a 6x6 setup. run 5 and 6 player games only (48 games per round, 43 per player)
4: the monster: 6x6 setup, run 4-, 5- and 6-player games. (96 games per round, 83 per player)
I love the thought of the last, but I don't see it as being practical. Cabin fever would set in HORRIBLY, and blood would be spilled.
Any of the others seems to be a reasonable possibility, and they can be played 'straight' or 'shuffle' for the elimination round.
Speaking of the "Shuffle", what did everyone think of THAT FEATURE specifically? Advancing past the first round by comparing your score not to those you PLAYED, but against a group (that you never played) that played the same folks as you?
...You played it, and you still don't know what I'm talking about?
