I bought the Core set awhile back and finally got a chance to play a few games last night. I've got some questions...
1) Can you put neutral cards on your domains to use as resources?
2) Can you play "events" at any time, pretty much?
3) When a card has a cost of "X" is it possible to play this card at zero cost? There's a resurrection-style card that brings back characters from the discard pile, and some characters have a cost of zero, so can you play this card on those characters?
4) I'm familiar with the "resource match" thing about paying for cards, and I'm aware that some cards have a requirement for the resource match of more than one of that type of resource. I'm fairly certain that this is designated by having two (or more) symbols next to the title of the card. So, there's a Cthulhu card that has this - two Cthulhu icons next to the title - but this card has a cost of zero... so why would it have this requirement? It doesn't cost anything.
