All this debate about vacation days is quite tedious. What about a big fat achievement for those that use no vacation days during a 12 month period (for pawns - no timeouts?) and at least 50 games must also have been completed in this period (avoids inactive accounts being awarded).
What about an award for the one who finds the most Easter eggs in BrainKing?
"An Easter Egg is a hidden feature or novelty that the programmers have put in their software. In general, it is any hidden, entertaining thing that a creator hides in their creation".
trohat: Correct, I had thought that through, for some it will be impossible, some luck, some easy. For the latter, it becomes a 50:50 probability. (edit: actually it's a probability of 1 if it is a 4 or 5. That's if you haven't resigned by then! )
Fencer, your idea of "Would you dare to win Espionage by capturing opponent's base without revealing it by a spy?" is good but rather easy. Just capture it with a sab! Perhaps modify the achievement to "Would you dare to win Espionage by capturing the opponent's base with a 4 or 5 without revealing it with a spy?"
