While I know this will never happen again probably, but I'm still going to say it. Personally I really want Gem Hunters back. I loved Gem Hunters when it was a thing and played it a lot from what I remember. I loved it because it was a grinding game where there was never really and end which was a fun type of game to have on the server. However, I feel like this will not make a return due to the massive amount of bugs and developer time it took to keep it up. However, I would love to see it make a return. As for a much higher chance idea I would have to say updates to SG and Bridges, as those are some of my favorite games.
