A lot of people got in at the wrong time. A lot of people did very well and some people said, "This is it. I'll never get back in again. " And they maybe meant it, but they probably got back in again anyway.
For me, Modern Warfare 3 's plot makes its signature turn around the bend when Russia invades Europe. As in, all of it. Simultaneously. Now, I've never invaded Europe, except for that one time, but I would think that's a project you might want to stagger out a bit if you haven't forged an alliance with any galactic empires lately.
