Marvel Champions has been my first LCG. I can see how these things become a problem. Between monthly releases and Etsy, it can get out of hand pretty damn quick.
I can only imagine how this will be when they start producing decks for heroes and villains I actually give a damn about...
Been playing this solo game, too. Everything Lost is a very small production run (200 copies) zombie apocalypse survival game out of the Netherlands that uses a very clever action card system. It drips with theme and each of four chapters in the campaign plays in about 45 minutes.
If you have a change to play Pax Pamir, especially the 2nd edition, you should. If you like contentious multi-player tableau-builders with many opportunities to flip the board, it'll be up your alley. The designer, Cole Wehrle of Root fame and a Lifetime Longhorn, took a lot of time to include painstaking historical detail. Things like the zero sum nature of the economy of the time (19th century Afganistan) is reflected in the economy of the game. I enjoy reading the factoids about the historical figures as much as I like using them to assassinate a character in a rival player's court. Neat stuff!
And for more family fun, Calico is a cat-themed game that plays like trying to solve about 7 different puzzles at one time. It's easy to learn, difficult to master. The only interaction is possibly taking a tile from the market that someone else might want - so it's a great game if you want to keep it PG.
Also played a bit of Smartphone KS Edition which feels like a more simple Food Chain Magnate. But, unlike FCM, it isn't murder on the eyes.
And I introduced Raiders of the North Sea to the in-laws. We played with all the expansions and a great time was had by all. Side note: The official neoprene mat is the most vibrant neoprene play surface of any I've seen, period. It's on sale right now in the Garphill store if you're interested.
One of our favorite genres is whodunnits. We're going through the base game of Detective: A Modern Crime Board Game and after finishing the base cases in Detective: City of Angels we've started the first expansion Bullets Over Hollywood, with the expansion that just came out, Smoke and Mirrors, waiting on the shelf.
And now, dear reader, you are pretty much caught up.
