Alright guys, several people have mentioned having a titan that doesn't just show up to tear the universe to pieces. Now, I'm open to ideas, but this is going to be a hard sell. The idea of the Titans is that once (or maybe a couple or three times in a long game) a titan will show up somewhere in the universe. This is supposed to be an “Oh man!” moment that is going to take some interaction to resolve. With the world destroyers it's very simple: You need to get them on your team or get rid of them. You don't want them wrecking up your stuff and you sure don't want the enemy finding a way to get their help.
So, how can we give players that feeling with some goody-goody?
