Probably would be better with a few ground rules:
- At least half of the titles must be first-party
- There should be some diversity in the third-parties (i.e. not all Konami or Capcom)
- The system should aim for genre diversity as well
- No licensed titles (that just gets messy)
- Huge sellers and important genre-defining games should receive extra consideration
That's about all I can think of now.
