It's been a good year, gaming-wise:
GMing:
Wrapped up a 5E campaign for newbies to the hobby that begun last year. This went on for 36 sessions in total and incorporated some official material like Forge of Fury. I'll migrate this group to a different ruleset and setting for the new year and a new campaign, likely Hexxen 1733 (a German baroque-era / fantasy RPG) or Forbidden Lands, should the former fail to convince.
For a different group that started in the summer, I ran the Symbaroum Copper Crown trilogy and we just recently moved on to the first book of the Throne of Thorns campaign. 11 sessions in total so far.
Several one-shots, mostly Call of Cthulhu (maybe around 5 in total), as well as single forays into Mothership (the Adrift scenario) and most recently Imperium Maledictum.
Playing:
In a Curse of Strahd 5E campaign, 25-ish sessions in. I've burned through three characters; they all had it coming and it's great fun.
A one-shot each of Mothership, Pirate Borg and an OSR game.
