@dave_tacitus: Wow you are dedicated. I just filter my games by whether they are installed or not.
If I learned anything from this thread, it's that a lot of games do not fall neatly under a specific genre description. Technically most horror games are just adventure games, Capcom just made up the Survival Horror label to market Resident Evil. Then of course something like Dead Space is closer to being a third person shooter than an adventure game.
And on the RPG front, we have western games like Septerra Core and Anachronox closely mimicking the gameplay systems of what is popularly defined as JRPG.
