I think the SE Olympics (expanding it from the LT challenge) has the most possibilities for fun.
(yeah, I'm commenting though I will follow Geo's lead of helping the USA team by NOT playing)
And, of course, another hand in the pot makes it difficult to stir properly.
But...
A few random suggestions (these are directed toward a worldwide olympic style approach):
- Smaller teams make for better moving games. I'd suggest 3 at a max and possibly 2. In the case of an odd number of players wishing to represent their country, I suppose a team of 3 or 2 would be workable. Also, this would allow for more countries who can't field a team of 4 or 5 or 6.
- Geo's comments and suggestions are very worth listening to. A team concept with a solo addition is similar to the real olympics. It would take some more management, of course. In concert with the above comment, it would also allow a person to at least represent their country if they happen to be the only one available.
- Once a format (what is and is NOT allowed) is decided upon, no variations should be allowed throughout the whole challenge.
- If it goes olympic "worldwide", then the duration could justify a small webpage. Also, while each person is representing their country, I'd suggest a small banner graphic in each person's "signature" to signify they are a representative in the Olympic match. (I'd be glad to design it for each country using their flag integrated with a simple "splash" if there was enough interest)
Anyway, just some thoughts. The thread has incredible interest and activity so I couldn't keep out of it...
