So far my understanding of the game's distribution is this:
Adventure Packs: Quest content with small bits of exclusive content for heroes and encounters
Deluxe Expansions: Premium sets containing interchangeable content that can be used with any Adventure Pack
Saga Expansions: Premium sets containing quest, hero and encounter content that directly associates with the LOTR story and its protagonists
So if I have this down correctly... assuming I do want to purchase all of the game's content over time and try to maintain a "complete experience" feel to things, should I begin with a Core Set and the three Deluxe Expansions, then purchase the Adventure Packs chronologically over time to keep the experience feeling "episodic"? The Saga eExpansions intrigue me but since those follow the LOTR story more directly, I'm anticipating a slightly more linear narrative and I'd want that experience saved for the very end.
Can anyone who's played the game's expanded content do me a huge favor and let me know if I have the right understanding of this? I'd really appreciate it.
Also, what are players doing for a more "hardcore survival" replayability mode? I saw something about Nightmare Decks but is that simply a type of retail deck or is that a game mode that can be used with any of the game's quests?
