As a prequel post to the series, I should begin with https://last.interi.org/2012/03/old-school-hack/. It is short enough to repeat here:
Old School Hack is a role-playing game that combines Red Box type D&D with modern game design.
It is available as a simple to read PDF (2.9MB), and if I were you, I start doing just that. OSH will become very important in the immediate future, so stay tuned.
Old School Hack was hot and new, having just been released in 2011! Unfortunately… the game hasn’t been updated since. It is really interesting, though, and that PDF link works, and is a very pretty document itself.
Now I wish I had built a directory of the games, rather than blogging about it. This is essentially a bit of information I needed to stick somewhere. I am definitely going to build a game directory!
