Ok i own the base game and the four small expansions, i thought a good idea to summarise what i frequently use off those packages and the stuff i never use. Also i will value with points from 1 to 10 the utility or added value we think the expansion has.
CURSE OF DARK PHARAOH old version:
I use new allies and the spells.
I dont use the exhibit, the barred cards, benefits and detriments, the dual gate or the surprise rule, nor the mythos or other world cards.
Except sometimes when we play a thematic EGYPTIAN game.
Points: 3 of 10
LURKER AT THE THRESHOLD:
I use always the new gate markers, the spell, common items and unique items. And sometimes the herald.
I dont use the relationship cards, dark pacts, mythos or other world cards except when using the herald (aprox once every 15 or more games.
Points: 5 of 10 primarily for the gate markers.
BLACK GOAT AT THE WOODS:
I use the 9 monsters and sometimes the herald. We have also a house rule for corruption cards, in fact we give those when players are sent to asylum or hospital.
I dont use the one thousand cards, mythos or other world cards except when using the herald once every 15 games.
Points: 4 of 10 monsters are a rare asset!!
KING IN YELLOW
Alway use the yellow tokens and the blight cards, in fact yellow tokens are always added in my games when terror increases with no need of the king in yellow to be present. Also the riot monsters are a must.
We dont use act cards, special magical effects except when using the heral once every 20 or so games.
POINTS: 5 of 10 mainly due to yellow tokens idea.
Summarizing, i guess every expansions has something great to add to games, a few of them simply awesome (like yellow tokens and new gate markers) but thematically we get tired of the heralds and extra stuff that tend to somehow increase playing time with no great add value.
Nonetheless, with only this foru expasiones we were able to build a common item, spells and unique items dech wothout repeating a single card and that alone is added value.
So in general i think i give a 4 of 10 to expansion.
Would be great to know your opinions.
cheers!
