For people who enjoyed Portal 1 & 2, there is Portal Mel and Portal Reloaded. I believe these two games were produced by fans of the series, so it doesn't have the same production value of the originals, but for those who really want to continue the series, it's worth a download, especially, since they are both free.
I downloaded both at Steam for free. Both games seem to have more challenging puzzles, so I wouldn't recommend playing these games, without first playing Portal 1 & 2. My first impressions are that Portal Mel is done better, than Portal Reloaded, but plan on finishing both, before World War 3 ends the world. haha!
