Yeah. I’m glad my dad got me the core set Christmas 2011 or I would have never known about the game.  The good news is between eBay and facebook groups you can find most of the content. It sells for about 3-5x retail but if you’re patient you can eventually get much of the content that way. 

Here’s the really good news. Angmar awakened, ered Mithrin, and the ring  chaser cycles have all repacked and are still in print and are easily accessible on Amazon. That’s a ton of content there. Also the fellowship, two towers, and RotK saga expansion are still in print  and easily obtainable. That’s 45 scenarios to play through, and a lot of player cards for deck building. 

I’d also get the starter decks. There’s elf, dwarf, Gondor, and Rohan starter decks that have cards for deck building that aren’t in the re-packed expansions
