I actually like it. It may not have many good games on there yet, but this works to keep things simple and you can tell what you are going to get in each section and page quickly and accurately.

League tables are always a good idea, so good to see that. Plus having community forums would be good too. It would help if you allowed feedback on games as an indication to new visitors what is popular or fun.

Also, for new visitors, why not try something different but fun such as a quick personality test that can be used to then recommend some games.
