Well if you're really, really interested in getting all the gory details, of course check out the BGG reviews. In short, Inns & Cathedrals is the simpler of the two expansions, just has extra tiles that double the value of roads and cities if you complete them with those tiles -- but now those roads and cities are worth zero if left incomplete. Traders & Builders brings more to the table. Now you have city tiles marked with one of three goods and if you complete that city you get that # of goods (regardless of whether you had any knights within). Also the builder lets you get an extra turn if you add to a road or city where he is and the pig lets you get some extra points for farmers.Suairyu said:Expansion packs almost cost the same as the main game, though! If you had to pick one of those expansions, which one would it be?
Side question: do you guys tend to keep all expansion tiles/cards/chits/models in their own boxes or just fling everything together in the original box? Carcassonne's box is already near-full with the original set of tiles, but independently separating the original from the expansion tiles at the end of each game for filing in separate boxes sounds like it would get dull fast.
I find I&C a better first expansion because of the simplicity. I also think T&B works best with 3 or more. So I'd recommend I&C even though T&B is probably slightly better and meatier overall.
I got the Big Box set which comes with I think five expansions. I keep my base + I&C + T&B tiles mixed since that's how we like to play.
