Hmm. Arkham Horror LCG officially was released in November/December of 2016, but just the core set. The first proper adventure cycle that wasn’t mostly a tutorial for it arrived in January/February of 2017.
Looks like only two people mentioned it in the previous vote. The ever-forward looking Charmtrap had it on his list at #5, and McMaster had it as an honorable mention and something to watch.
I might be stupid and put it on my list, since its release dates kind of fall through the cracks here.
