One of the following must be true: 1) I misunderstood the rules of game 2, b) game 2 is trivially broken, or c) an expert can somehow extract a messaged that you've xored with a random pad and then destroyed the pad, in minutes.

I'm guessing (1). First, One-Time Pads have already been invented. Second, you're unlikely to find someone willing to spend the time to extract plaintext from an unspecified ciphertext; the idea was to give your full cipher design up for scrutiny. After all, if it's truly secure, it will remain secure even if the attacker knows how it works.

But I thought the whole point of public review of ciphers was that amateur-designed ciphers have a high risk of being broken by experts, even if they aren't told what the cipher is?
