Fun idea, im joining. Things i finished this year:
AoS: 32 dryads, 3 kurnoth hunters + weapon options. In the process of painting Awlrach and a unit of Bladegheists. Finished building the Warsong revenant.
40k: MANz unit with all weapon options, Deffkoptas and a unit of Boyz with shootas.
Things i received: Hunter and Hunted Warcry box, Hedkrakkas Madmob, the Bladegheists and Awlrach.
Out: 9 units
In: 5 units
Overall i would say i did good this year. I also painted and build a lot of terrain for my games. I did cheat a bit and bought my first gunpla kit (MG Ginn) with more on their way for Xmas. I definitely need more shelves. Now some pictures.
