This is by no means an exhaustive list of places to go, or games to play, but it's a starting point, and if you can't eventually get there via one of these sites, it probably doesn't have anything to do with role-playing games.
- The forge
The focal place on the web to talk about "indie" role-playing games. Indie, in this context, means creator-owned, published and controlled. The forge closed in 2012, but is still a fantastic archive of information.
Rpg.net is the single biggest forum and focal point for role-playing games on-line. Reviews, discussions and all that jazz.
Anyway is the weblog of Vincent Baker, of Apocalypse World and Dogs in the Vineyard fame, where you will find top-notch theory discussions, as well as links to a schwack-load of other game and game-theory weblogs.
- Half Meme Press
Half Meme Press is where My Life With Master resides, which is the first independant game I had any serious exposure to. It absolutely changed the way I think about role-playing games. There's other stuff there too; Paul Czege makes good games.
- Black and Green Games
Black and Green Games is where Emily Care Boss wears her game designer hat, and it's a heck of a hat. She's the designer of Breaking the Ice, which is a magnificent game, and probably the single most approachable game in the entire role-playing hobby.
- Hellequin Games
Eric Finley is the creative genious behind Hellequin Games, and I use neither adjective lightly. His games are both better and prettier than mine.
- Indie Press Revolution
IPR is a fulfillment house that pulls the cream of the indie gaming crop. You could game every night for months on top-flight games without ever going anywhere else.
- Ad Astra Games
Ad Astra is where I first cut my teeth on 'behind the scenes' game production. In the latter couple of years it was being worked on I did a lot of playtesting, design discussion, rules proposals, full-on writing of both fiction and game rules for Attack Vector: Tactical, Ken Burnside's labour of love. Ken Burnside and Scott Palter have been immeasurably patient and supportive in my first fumblings and flailings into game design and production. AV:T is also flat out one of the best games I've ever played in my life - one of the few to acheive the holy grail of science fiction gaming: playable AND plausable.
