Better Searching of the Wish list, while the most voted list is nice, I think it does lend an opportunity for some games to be omitted, as users peruse that large list and get fed up and then just click on the readily available. Some one also mentioned a way to prune this list as well of all the double entries, this too is a keen idea. Sorting this list by title, genre', or number of votes would be helpful. There are some others but getting that information to begin with may be tough: year released and Publisher info could be big on that list.
Besides the Games list itself, and these boards, the majority of my early time will be spent on that list, perusing what may be coming, and making sure that my Good Old games of choice have made the list as well.
