that is what I dont understand. If the person that bid on apollo always gets to bid first in the next round then that person can always bid on apollo again. in a 2 player game that his a problem because he is getting a cornicopia every turn.
You could do this but there are two other rules that help to balance it so people don't do it. Apollo can never buy creatures. Bidding on Apollo doesn't directly provide any means of winning the game.
In a two player game (or any number of players) if you take Apollo immediately every turn, you are guaranteeing that your opponent gets a god for only 1 coin. Having a lot of money is good but mostly for up-bidding because most gods (Except Zeus) suffer from diminishing returns and you don't need a lot of money to hit those returns. For instance, Athena for 6 gold you have bought everything she provides.
