1) Make the "I play this game" button/link more prominent and easy to use
2) Fix the anticipated games feature (i.e make it do something, or change it)
3) Add a developing aspect to the site (My contributions, I contribute to this game, etc.)
4) More space for game icons/classifications/attributes (they seem a bit crowded now)
5) Different attribute icons (the current ones are a bit similar. The icons could resemble the genre, for instance)
6) Allow for more user contributions! (update games, listings etc.)
More to come!
