I'm looking to get into LCGs after a long time hating on CCGs, having been lured in by FFG's upcoming release of Android Netrunner. Call of Cthulhu will be my next investment likely, but I'm curious about a few items.
#1 - I get that the Core Set is needed for getting the fundamentals, but what are these different expansions I'm seeing? They range from $15 to $30, but I'm unsure what to expect from their contents. Do they expand out specific aspects of deckbuilding? Factions?
#2 - How often do you see expansions get released? I like setting aside some "fun money" each month to keep myself from buying too many indulgence items, and I want to know how often I should expect to buy.
Thanks in advance for any help, as well as any links if these questions have been answered many many times before here.
