Uh, what? Adventure game - more or less - is always tied to luck factor (I hope for less). WAG is not eurogame and should NOT be the one. Didn't you notice lots of dice? Ameritrash at its finest.
Properly controlled luck factor can be in the game without making it push your luck game. Games like Kingsburg or Stone Age has lots of dices but luck control measures are installed such as dice modifiers, number of dices used and alike to keep the luck in check. It's possible in those games to decide how muck you rely on luck vs safe choice. It's possible to make an adventure game with randomness and controlled luck. I would imagine it's possible for adventure game to be something like Pandemic with more complex rules to accommodate adventure in it. Yes, I definitely prefer "eurogames".
