Yes, I will. I have platinum. But just in case, bring a disk with you.
And how do they choose colors from 3 or 4 possible options? It's not specified in the rules.
We didn't have any color selection process; it was done like this: the first player writes down 2 colors on a piece of paper - the main one and a backup. After that, the second player (in our case, the one with the advantage in choosing) simply says which position they will play. If that position matches the first player's choice, the first player will play on the backup.
Another unconsidered "bonus," although not the most important, but it's better to clarify it - the AI races. IMO, let the first player choose them, but they must all be different and different from the players' races.
