Man, if you don't like the mats, don't use the mats.
Have yourself a little mat bonfire.
If you're worried about the increased cost of having mats and tokens in the expansion, I feel for you.
But it's going to be a fractional increase in the cost of something that is a luxury purchase anyway.
MSRP is the same as other expansions
Well, it's the same $44.95 as Intrigue, Prosperity, Seaside and Dark Ages.
Which all either have 500 cards
or have 300 cards plus mats/tokens.
Hinterlands is $5 cheaper, with the same number of cards as Seaside & Prosperity, but no mats/tokens.
So, we can't really pretend that the mats/tokens have zero impact on the cost of the expansion.
But given that Adventures has 400 cards
and mats/tokens, I think a MSRP of $44.95 makes it a relative bargain.
Especially when you factor in that it has
sixty tokens, which is about the number of tokens in Seaside & Prosperity
combined.
