Interesting to note that each starter in the Interdominion must pay a $10,000 starters fee.
With 14 starters that's $140,000, so the final is not $750,000 but $610,000.
Added to this, each starter finishing 5th to last will have $15,000 added to their prizemoney total with the $10,000 deducted starters fee not allowed for. The owners get $5,000 to cover their expenses, granted the thrill of making the final would be outstanding but maybe it's not the money maker it appears to be.
Good luck to all starters
