Back in August of last year, I wrote about a nifty one page RPG called Searchers of the Unknown RPG. Searchers of the Unknown is a one page set of rules for playing old-style (aka early TSR) D&D modules where the characters are no more complex that the monsters: a one line stat block. SotU does a great job of capturing the essence of old school D&D in a tiny set of rules. Rules that even make the hated by many descending armor class used in old school modules useful.
Searchers of the Unknown has become quite popular. A number of expansions and variant games for different settings have been written by people who like the game. Here is a list of the variants I'm aware of. If you know of any more, please add them in a comment.
