Super Smash Bros. Brawl stage editor is a great way to extend the value of the game, but it's only really valuable if you and your friend-code friends have the creativity to come up with interesting stages. Those of us with no creative talent and/or no friends are out of luck!
Enter the web, which has already filled in some of the stage-sharing holes Nintendo left in the game. IGN's recently launched Smash Bros. supersite already has a selection of over 100 user-created stages that players can download to their SD cards, while the Smash World forums Stage Browser currently has 85 or so stages available. Each site offers picture previews, easy instructions for uploading and a rating system to separate the wheat from the chaff. Now if someone could just hack a way to play these user-created stages in online matches we'd really be in business!
