The editor has very great potential. The problem is 90% of people don't know how to use it well and we get dota, tower defense, etc... But the amount of stuff we have seen in the editor so far has a huge potential. There are single player dead space style games in production, for example. The sc2 editor has almost limitless possibility. As of now there are only a few maps that are really awesome. I don't actually do much custom gaming, I just use the editor.
