Not only is this the best game I've played all year, it might be one of the best games I've ever played. Honestly, I haven't been this addicted to a game since maybe Final Fantasy XII or Dragon Quest VIII. So hard to put down.
Also, I find it amusing that the only real reference to Portable Ops I've encountered thusfar is Kaz saying something along the lines of "thank god we can finally leave that crappy place MPO took place behind." Yes, let's. What a colossal waste of time that game turned out to be.
