Doesn't guide you enough.

Game: Free-Games.com.au

I looked around, tried to add my own game, and realised I had to log in. I registered an account, logged in, and tried to add my game yet again... but it finally told me I needed a link back. I just gave up after that. Too frustrating.

For the record, most of the games listed in this directory are crap... if not all of them.
