I think the description of the cube game is ambiguous, and I initially misunderstood it. I'll start off by saying, no shade to the AoC people, and I greatly appreciate and respect their efforts. Just pointing it out.

The intended meaning is that in each game, a set of red, green, and blue cubes is taken out of the bag, replaced, another set is taken out, and so on until the game ends. I think the example can be understood in the meaning that all sets listed for the game are taken out and replaced as a group. That is, these are mutually exclusive subsets of the bag's contents. The example only shows games that are strictly valid or invalid for both interpretations. It didn't show a game that had individually valid sets but a sum of some color that exceeded the maximum. For example,

Game N: 4 red, 5 blue, 4 green; 3 green, 2 blue, 7 red; 2 blue, 8 red

would require at least 19 red cubes by my initially understood meaning, and only 8 red cubes by the intended meaning. The misunderstanding can be disproved from the part 2 description, but I was on part 1 at the time. The phrasing of the rationale for invalidating games 3 and 4 in the example perhaps leans towards the intended meaning, but subtly.

Why, oh why? A choice between four American multinationals is no choice at all, IMHO
