Over the years, I've presented here a number of series of posts about how I think rpgs work. Some of them were fruitful, some less so, but here are a few of my favorites.
2010-02-23 : Can your brains just do it?
2012-03-19 : If it isn't an RPG, is it still an RPG?
2012-12-26 : what about Resource and Effectiveness?
Thanks for this! That "IIEE with teeth" post is something I've been thinking about lately, playing Blades in the Dark. Nice to have it just there!
