Glorious Trainwrecks used to have star ratings for games, but Jeremey dropped that last year, feeling that ratings discouraged people from commenting on games. could discourage people from making games. I also don't think that public ratings are always a solid indicator of what games are subjectively good or polished! Or that the only games worth playing are those that had polish or effort put into them!

Currently the only curation is to pick a member you like, see their profile, and check out their list of favorites. I'd love to see this brought more into the forefront, maybe a page that shows you a random member's non-empty favorites list?. I don't think I'd want a page that shows the most favorited games, but I see how the site as it is now doesn't answer "what are some games I might enjoy playing to a newcomer." There's a tension between discoverability and reducing the site to one that implicitly makes creation into a competition.

(You can also see the most commented-on games, which also isn't necessarily a indicator of games a given person would enjoy playing.)

For genre, with the current site that might need to come from tagging? I don't know if I'd want to see putting down genre as a requirement for submission; tons of games on the site are all the better for defying genre conventions, and if searching over genre becomes a focus that would leave out the older, unclassified games.
