What I think you need to ask yourself is the following:
- How does my site differ from anything else out there?
- Why would a player want to bookmark my site?
- Is there any feature on my site which makes it sticky and gains repeat visits?

With the way Google is changing serps from one day to the next, having sticky content which grabs at players and encourages them to return is paramount to success these days in the online gaming industry because there are just too many sites that look the same and offer exactly the same thing!
