How do you guys store your LOTR LCG? I'm thinking of sleeving all the cards, but I'm worried about storage.
I'm not home right now, otherwise I would take a picture but I flip the included insert upside down which provides two grooves, one on the left and one on the right. The grooves are wide enough to hold sleeved cards. I use FFG standard card sleeves and they work great. Black for player cards, white for heroes, and red for encounter decks. A nice bonus from sleeving is that you can proxy cards easily as well since the FFG sleeves are a solid color on the back side so you can proxy with MTG cards or something for a similar feel.
I sleeve my heroes and player cards and for encounter sets:
1) Each quest is composed of multiple encounter sets mashed together. There's the set that is named after the quest itself (Passage Through Mirkwood, Hunt for Gollum, etc.) and there are other encounter sets that are part of the base cycle (Dol Guldur Orcs, Spiders of Mirkwood, etc). The quest cards are usually only used for the single quest itself (exception is Journey Down The Anduin) while the shared sets are used by multiple quests throughout that cycle.
2) I sleeve just the shared ones and when I want to play a particular quest, I unsleeve the old quest cards I was playing with and just sleeve the new quest cards. So unsleeving/sleeving isn't too bad since it's just one encounter set to deal with.
I just made ghetto dividers using index cards but you can download nicer ones from Boardgamegeek if you want.
I have cards from Core and 3 Shadows of Mirkwood AP packs and everything fits very well in one column of the original box with the insert flipped. I can probably fit a few more AP packs before I need to start on the second column.
