I've already subbed. You should give new games at least 3 months when launched as they generally add content within that time that they couldn't release during launch. It's kind of like a new show, you should give it 4 episodes before making a decision.

That is of course unless you really hate the game. I can say as of now, I know no one in my FC that is not subbing.

But let's be honest, this game was always going to lose at least 10 if not 20% after the "free" month was up. There is no way around this. The game will not die because a few people on the forum decide to leave. The real test for SE has just begun. They probably got a year to pull people into the game. After that, it's anyones guess.
