Rio de Janeiro
A thing that I thought flawed in the scoring is the overrated value of having half-tablets in your hands.
This was acknowledged and corrected by the designer. There is a FAQ/errata somewhere that says tablets are now worth nothing for scoring. The original idea was to give some compensation to players with unused tablets at the end, which would work well if everyone played "in the spirit of the game", but holding them turned out to be a viable strategy.
By the way, I think your post would suit better in the comments section of the game page.
