I think too many jackpots would make the game pretty unbalanced. I think if he wants people to vote he should just have the votes be related to the 1st place players power or credits if he is not around to change it. Even if every player were to win it once a round it would still be unbalanced depending on when they got the turns. Early round 2500 turns relate to more $$ from donations than late round 2500 turns would. Even without including the donations part early round turns have to be used more effectively than late round making them much more important.
Edit: With the votes being tied to the #1 player it can increase with the total net worth thing that was on so elite where creds, ships, segs, etc all tied in. Once a player reaches a certain net worth voting goes up. I think this would be the best course of action and not too difficult to implement.
This would get people to vote and solve the voting not increasing throughout the round issue
