As far as a common system goes, the RPG industry has gone back-and-forth. After the hobby was established, there was the movement where the game companies created House Systems so that their fans could easily transition between the product lines. The Indie movement is a reaction to the House System movement. There is always going to be this back-and-forth in the industry. There are always going to be people who like the standardization of House Systems, and there are always going to be people who want to push the boundries and play outside the of the box.
