I'm not usually a fan of big games either, but I think the complexity of the game you played was probably more to do with which expansions you included than the number of tiles as all that extra wood will have given you a
lot more to think about.
I can understand the wagon getting left out, but I do tend to use my mayor if I've got one and will always use my barn when a decent opportunity to place it presents itelf. Barn + pig can generate a lot of points if you use them in the right way
Perhaps you would have enjoyed the game more if you were more familiar with some of these components?
Maybe it would help if we had some way of calculating overall complexity of a game? My suggestions would be (very much open to debate):
Inns & Cathedrals - 1 star
Traders & Builders - 1 star
Princess & Dragon - 2 star
The Tower - 2 star
Abbey & Mayor - 3/3.5 star
King & Consort - 4/4.5 star
Bridges, Castles & Bazaars - 3 star
(all other expansions) - to be decided!
Then add the stars together to get the overall complexity of the game, so yours was a 5/5.5 star game.
If I'm using expansions for a casual game, I'll usually include I & C and T & B but won't include many more as few people I know are familiar enough with the rules. 2 stars is nice level of complexity for a casual game.
