I just bought the new expansion, but haven't tried it yet.
I got my area into this game way back in the day first cycle just after Horror Beneath the Surface. We didn't want to get really into it at first and held off on buying the first 4 LCG format sets. Sleeper, Surface, Mountain, and Ancient Horrors.
These seem impossible to find now. My group has raised a good question. How much do these 4 packs change the game? I looked over the Ancient Horrors pack and flipped when I saw I am missing so many awesome ancients.
We play for fun. Only using one unique in each deck. Helps Yogg feel special being able to resurrect and bring back people. But now we are wondering just how much are we missing by limiting ourselves to just 2 copies of core game (per player) and 1 AP (per player). We feel that since you draw 2 cards instead of one, like most card games, that having multiple copies isn't as big a deal.
Now I am just curious, as it appears I missed out on some great APs.
Thanks for the answers and opinions in advanced.
