Those of you who made it all the way to the bottom of yesterday's post will know I have chosen to go with Wrath of Kings as the system to focus on in 2016.
Wrath of Kings satisfies all the criteria I was selecting against when winnowing down the systems available. It's 28mm, with some really nice models, interesting rules (especially for army building), and solid background.
The different Houses of Wrath of Kings have incredibly different looks, and all avoid standard fantasy tropes. There is nary an Elf or Orc in sight. The models look great, and there is wide variation within the individual Houses.
The game should scale well from a small number of models to a full clash of armies, which allows me to start playing games from the very inception of my collection, and not have to start rotating out units as it grows.
The background for the five Houses is very solid, as is their motivations for going to war. The world also gives serious leeway for any force fighting any other force, (a major failing of the old Warhammer Fantasy, where some forces required major narrative gymnastics to even meet (looking at you Wood Elves)).
Having picked a system the next step is to make a start getting my hobby skills back up to scratch, and lay my plans.
