Just played a game with a pretty crazy combo that I never saw in testing...
Alien Egypt and Gang of Pickpockets. Now, Gang of Pickpockets is already a very strong card if you draw it early. I have it ranked #1 in the original set; haven't tried ranking cards from the expansion. But anyway, at least you still need to get other cards to score.
In my last game, 1 player went to Time III to play Gang of Pickpockets. Then, he went to Time III every single turn for the rest of the game, until the last turn when he went to Alien Egypt to declare victory. Never any reason to go anywhere else.
Now, his strategy was helped by 2 other factors:
1) The 2 different zones in Time III that were real at different times both gave extra money (+
for each card you drew this turn, and +
for each other player here). We were playing the "They have arrived" suggested setup... that board definitely seems geared to make Alien Egypt stronger than normal due to the extra money generated by Time III.
2) He didn't draw cards that gave low money with some other effect, like Secret Society or Beggar.
So perhaps it was just good luck as a whole. But it was definitely primarily driven by just having Gang of Pickpockets in his opening hand on an Alien Egypt board.
