It took you four years to see that you're laying tiles to score points in two tile laying games?
I may have thought of it before, but today I was thinking about how you can play in certain ways in each game to ruin certain other possible plays you might fear could score well for your opponent(s). But really I was primarily thinking that Carcassonne is a better game from the balance standpoint. In scrabble it can be a nice lucky break to end up with a triple or double word score available with a 7 letter word that involves the letter Q, or like average, you can make a play for 5 to 20 points using average pieces and average multipliers.
In carcassonne the playing field is more leveled. There's still lots of luck, but choices you can make to make luck not as important for you and your meeples.
