This project had an interesting reward structure - the first 200 supporters were allowed to pledge as little as $5 (though many pledged more than that), and the next 500 "pay what you want" supporters pledged a minimum of $10. The regular pledge level for 1 copy of the game is $20, and retail price will be $25.
This overfunding goal presents the early adopter with an option that later supporters do not have:
1. Keep my pledge the same, and receive a 2 player game for an extraordinarily low price.
2. Up my pledge to $15+ and receive everything I was going to receive, plus tiles for 3-4 players.
Both of these are good deals, depending on the desire of the supporter. And it makes sense that there be a minimum pledge level for the overfunding reward, because doubling the number of tiles will severely increase the shipping costs. I don't see how $5 could cover that!
So if you're a supporter already, then thanks very much! Depending on your pledge level you might have a choice to make (super low price vs 4 player game). If not, consider jumping in - any of the reward levels above $15 will come with one set of the tiles for 3-4p for every copy of the base game!
