I was going to post something else, but I was distracted by a Warlord announcement about yet another 'boutique RPG game' [(c) Mike Hobbs, 2013], namely a Terminator tie in, which caused me to sigh 'what, again?' rather.
Let's break down our top 20 from a couple of days ago into some broad categories you can all disagree about in the comments section :D
20th Century Historical (Platoon-): Chain of Command,. Bolt Action, (Dead's Army)
20th Century Historical (Company+): Battlegroup Overlord(etc), Flames of War 'Nam
20th Century Air: Wings of War
Pre-1900 Large Scale Historical: Black Powder, WAB, War and Conquest, Death In The Dark Continent,
Pre-1900 Skirmish Historical: Dux Britanniarum, (WAB campaign) Bushido
SF/Fantasy Large Scale: Warhammer, Oldhammer, 40K (sometimes), Future War Commander
SF/Fantasy "Ship": XWing, Battlefleet Gothic, Dystopian Wars
SF/Fantasy Skirmish: Deadzone, Warmahordes, Judge Dread, Dreadball, 40K (sometimes)
Interesting: I was expecting, before I started counting, more games that fell into the 'boutique RPG-lite'/Necromunda 'gang' category, or whatever you want to call it, especially with single-manufacturer setting-specific figures. It's pretty much a 50/50 split between historical and not, in terms of games, but probably weighted towards not if I could be bothered to count number of players (which I may do this year).
I'm sure there's a conclusion to be drawn here, but I'm coming down with a cold and it's escaping me. :)
