One suggestion that I think should be implemented:
When using the search box on the site, it only finds games based on the order of the words you put in.
For example, I was just searching for Mario & Luigi: Bowser's Inside Story to add to my collection. The site can't find anything if I put in just "Mario Luigi". Contrast to GameFAQs, where it will display all games containing the words "Mario" and "Luigi" in the same title (basically, all 3 M&L games show up).
I tried putting in "Bowser's Inside", but the site automatically adds a forward slash before the apostrophe after you press Enter, so you can't find anything that way either.
Ended up just putting in "story" to find the game.
For a search function on a website, anywhere, you shouldn't have to be picky about what it will accept. What I'm basically saying is you should be able to find the game you're looking for if you put in any word in the title, in any order.
Another example: the site produces no results if you put in "Zelda Mask". You would expect Majora's Mask to show up.
I know it's being picky, but for more casual browsers, you don't want this pickiness. Hopefully I'm making enough sense, and that it shouldn't be too hard of a thing to implement.
