Games I've played for the first time in the last couple of weeks (in addition to having familiarised myself with and nearly overplayed Avalon and Monster of Tokyo recently) --
One Night: Ultimate Werewolf
Love Letter
Hanabi
Ticket to Ride
Takenoko (aka Catan: Harvest Edition)
Cosmic Encounter
I like them all, but I will comment on two of them.
Cosmic Encounter stands out as having the most rules and structure to remember, and it's not my favourite sub-genre, but I enjoyed the card management and negotiation elements. However, I am so envious of other players who pick up multitudes of new rules so quickly. I am such a visual person so when someone is reading out a bunch of stuff and even explaining themselves, as convincing as it sounds I just don't absorb the words, whereas instantly other players are asking appropriate questions, or laughing at the right moments when a joke is made that isn't obviously a joke, or quickly skimming through a card's powers and going "OH REALLY?? WOW OMG THAT'S AMAZING THAT WILL HAVE SO MANY IMPLICATIONS FOR THIS OR WHEN THIS HAPPENS ETC OMG" whereas for example I'll be reading some card thinking "yep, that written information is a bunch of stuff" ... anyway, ultimately the strategy itself is relatively simple to carry out (although there is obviously advanced strategy possible) and it's all rather visually clear what's happening, in what order, etc.
The opposite and yet the same sort of applies to One Night: Ultimate Werewolf, for me, in that the concept itself is simple (there are a small set of cards, usually 5-10, each with an associated action performed at a certain time when everyone's eyes are closed) so it's easy to get the ball rolling, to pick up and play for newbies, but the gameplay -- keeping track of and visualising the different scenarios and possible solutions -- is just too hard for me. In fact, after playing about 10 rounds I still am absolutely confused about when and why to lie or to conceal information, and without being able to follow everything easily, I just decide to sit back and let everyone else accuse each other (occasionally sitting in to play along with made up assumptions), and at some point (if a villager) will announce the truth and see what happens. In this case, I'm envious of how other players upon learning the game, can 1 round later know exactly what they're doing and perform flawless strategy. But I know others are exactly like me -- others don't know what the hell they're doing in terms of strategy or lying or whatever, and I don't know if it's because Avalon is just easier or it's more visual, but I and practically everyone else who has played Avalon has cottoned on really quickly about different strategies, but people have been sitting in the dark a bit more with Werewolf.
