Sleeving
I have not sleeved very many games. In fact, I think the very first game I ever sleeved was Lovecraft Letter, and thatās only because it came with sleeves in the box!
After that, I did sleeve Inis, because the cards are lovely (and good thing, as a friend spilled her drink while we were playing and it saved a few cards that would have otherwise been ruined). I sleeved Star Wars the Deckbuilding Game because the deck was so big that when I tried to shuffle the cards, they started showing wear almost immediately, so the sleeves felt necessary to not have the deck deteriorate after just a couple of games.
Finally, I started sleeving Unmatched, as I just really like the game, love the artwork on the cards, and the first deck I did was Bruce Lee, which was out of print and supposedly never going to get remade. That said, Restoration Games managed to get the Lee estate and the Ali estate to agree to licensing for a Bruce Lee vs. Muhammad Ali set which will be released sometime next year, so those who missed out will be able to get Bruce, which is a really fun deck!
Oh, and I ended up sleeving Lords of Vegas because the cards were creasing horribly from being played so much.
Expansions
My history with expansions is kind of varied. There are some games where if I find the expansion for cheap, I will pick it up, even if I havenāt played the game yet, such as the Tennoās Court expansion for Shogun, or Rise of the Empire for Star Wars: Rebellion. Might be able to include Firefly here as well, as while I did solo the base game the one time Iāve had it on the table, Iāve purchased virtually all the expansions in the hopes of playing a big olā game of it someday.
Other times, if I have really been enjoying a game, I will buy an expansion for it to give it a bit of variety. First one I can really think of was Lords of Waterdeep: Scoundrels of Skullport expansion, which while not a necessity does add a nice amount of additional content, and we usually do end up playing with one of the two modules. Same with Istanbul: Mocha and Baksheesh, which we always use when playing now, Quacks of Quedlinburg: the Herb Witches, Taverns of Tiefenthal: Open Doors, and Concordia: Salsa. The most essential expansion I think I own, though, is Lords of Vegas: Up! The ability to raise your casino makes the games much more competitive and gives you options even if all the tiles for a given casino get taken or you get boxed in on a block. Legendary Marvel: Dark City is also a critical expansion, as it adds a lot more variety and challenge to the base game, which can be a bit lackluster otherwise.
Iāve also got the 7 Wonders: Leaders expansion which we typically use, though we havenāt played in quite some time now. Also a map expansion for Concordia. Oh, and all of Everdell since I have the Complete Collection box.
Sadly, I have a number of expansions that have never been used. Star Wars: Outer Rim: Unfinished Business (though I really want to, itās already sorted into the base game, I just havenāt had it on the table since), The Bloody Inn: The Carnies, Ghost Stories: White Moon, 7 Wonders: Armada and Babel, the aforementioned Firefly expansions, and recently the two expansions for Tokaido, Matsuri and Crossroads. Probably some other ones that arenāt coming to mind.
Oh, thereās also all the various decks for Marvel Champions, where I have some which I have not played yet, same for things like packs for X-Wing or Imperial Assault, or scenarios for Arkham Horror TCG. Have used some, but certainly not all of them.
