Ok, let's say we just started Power Grid game for 4 players: A, B, C and D. We will be focusing on
Phase 2nd, which is the first Auction Power Plants phase in the game. We have (randomly) determined initial player order, which we can assume is now ABCD.
Exception: In the first round of the game, each player must buy a power plant.
Ok, so let's assume that this is what happens in the first round's Auction Phase:
- A selects Power Plant, D wins the first auction.
- B selects Power Plant, B wins the auction.
- C selects Power Plant, C wins the auction.
Now, this would be D's turn to select the Power Plant, except he has already bought one, so he cannot bid nor offer a plant at auction.
Once a player has purchased a power plant in a round, he cannot bid in another auction in the same round, nor can he offer a plant at auction.
Does that mean we are back to A, and he selects Power Plant as the last player this round and therefore buys it at a starting price? Or was he obligated to choose plant again after D won the first auction?
Side note: I was quoting Official Rules found on RioGrandeGames.com.
