Play chess or hive if you don't like luck
drawing tiles equates to luck
Carc is simply not a perfect information strategy game.
That is sort of understood going in
Yes, and I
do understand that. Don't misunderstand me, I'm okay with it (although I
am going to have to check out Hive someday). I just prefer the expansions and rules in which the benefit does not rest entirely on who gets the best tiles. However, it really is very case-by-case. Each rule or expansion can be weighted more towards strategy and player control or more towards luck, and the sum of all these weights the game accordingly.
For example, imagine that, instead of pig meeples in Traders & Builders, there were six Pig Farm tiles (like the tile from River II). Theoretically, each player
could draw an equal number of Pig Farm tiles and get the chance to add them to the farms which they control. More likely, though, one player is going to draw more tiles than the other, and potentially get a greater benefit. In this scenario, I prefer the pig meeples, so I'm glad they went that route.
Another example: imagine that in The Princess & the Dragon, each player had gotten an equal number of dragon tokens, which could be played during your turn to initiate movement of the dragon. This would have the same result (12 dragon movements) with less luck involved. This would be a lot less interesting (to me, at least), since part of the appeal of the dragon mechanic is the anxiety: you don't know when the next dragon tile is going to pop up. In this case, I prefer this mechanic to be more luck-based.
Finally, an extreme example, just to drive it home: imagine that you didn't have any meeples at all. Instead, you got points for completing features. This would be really luck-based, and it would be a very different game (which would, admittedly, still have strategy; I think it would be a lot less popular, though).
I think that the base game of Carcassonne gets it mostly right. A decent balance between strategy and luck, with expansions and house rules that can alter the balance to whichever side you prefer.
