Drafting 18 cards, that implies a three minute long game. Triple that to account for handling of cards and scoring, and you have 7 Wonders in 10 minutes, minus setup and teardown, which still seems unrealistic. But it does get at one minor annoyance I have with 7 Wonders, which is that you spend a great deal of time on setup and teardown. You could realistically play Fairy Tale and draft 12 cards in 10 minutes, then spend 1 minute reshuffling the deck to play it again.
Race for the Galaxy has a better symbol language than any board game of its complexity. I normally complain about games that omit text for symbols to keep them language-independent, but only because nothing does it as well as Race for the Galaxy. Obviously it doesn’t work for everyone based on the number of people who have trouble getting into Race, but it 1) made perfect sense to me before my first game, and 2) is incredibly self-consistent, clear, and capable of conveying complex new ideas introduced in expansions.
I dislike the symbols on the 7 Wonders cards, they get it about 75% correct. The “discount” symbol that appears on Leaders does a bad job of conveying a discount, and the ‘once per era’ symbol is large and confusing.
