Full analysis below:
Wow. 154 plays spread out over 16 games in 2015. Given my "gut feeling" that I didn't get anywhere close enough time to game, that number is a lot higher than I would have expected.
I won't talk about every game on the list but did want to talk about the games where I had over 10 plays (on the basis that these are the "best" games I played in 2015).
Lord of the Rings: The Card Game
No surprise that this is leading the pack. I got this game in May and immediately fell in love with it. It's a brilliantly thematic game which combines the deep deck construction that you see in games like Magic but without all the issues that Magic has. The only reason it didn't get more plays is because its quite difficult for me to get hold of the expansion packs.
I fully expect this game to continue getting a lot of plays in 2016 particularly as the game works brilliantly as a solo game which makes it relatively easier to make it to the table.
Ticket to Ride
This is a really fun entry level Euro which I primarily play at work with some colleagues during lunchtime. This really should have more plays but sometimes, its hard to find the time to play - particularly when everyone is busy. Regardless, I expect this game to continue to get a lot more plays in 2016.
Yomi
Another great game which I rate extremely highly. Part of the reason that this has so many plays is that you rarely play just once when you play - normally going for a best of 3 or best of 5 to determine a winner. We even managed to get several multiplayer games which is an interesting twist on the normal 1v1 mode. Although I prefer the 1v1 mode, it was fun to try out the multiplayer.
Unfortunately, the rest of the group doesn't like this game as much as I do and its likely that the number of plays in 2016 will drop significantly.
Space Hulk: Death Angel
Got this game in February and managed 12 plays. This is actually surprisingly low given how much I enjoy playing this game and how quickly the game is to setup and play (relative to other games on this list). Part of the reason for this is the overall lack of time I have to play games. Another part of this is my buying Lord of the Rings in May which coincided with when I started to play this game less often.
Despite this, I very much enjoy this game and it will like see more plays in 2016.
Aliens: This Time it's War
This is a fun two player game which is actually available for free as a print and play game. Of the 10 plays this year, 4 of them were solo. This was either using the variant solo rules or with me playing the game 2 handed. While the solo rules are okay, my preference is to play 2 handed with me controlling both sides. The other 6 plays were with my main gaming buddy on the odd occasion where our game group session only had 2 players showing up.
Both my friend and I enjoy this game as it manages to capture the theme extremely well and it is likely that this will see more plays in 2016 (although I don't know if it will make over 10 plays if I don't play it as much solo).
