Face it. After its less than steller early success and quick fall to f2p, EAware didn't expect the game to last for two years, so they weren't really thinking ahead about what anniversary rewards should be. Then they suddenly realized "Holy crap, we're gonna make it to 2 years? Crap! Someone make something so they think we care!".
We just got a sizable expansion.
Maybe if you're a Lilliputian. Or a Lollipop Kid. GSF was better off when it was still the "secret project". At least it had hope while noone knew what it was.
