Even though I own all three originals, like a lot of gamers, I’ll be shelling out for Killzone Trilogy for one reason: the chance to replay the first Killzone game in HD (thank you Sony!). That said, where’s Killzone Liberation? That excellent (and under appreciated) PSP exclusive was quite a solid chunk of side story action that, despite the third-person viewpoint and bird’s eye view camera angle, still looked and felt like it belonged in the canon (which it does). I’d have added it as a free PSN download if there were somehow no way to fit it on a disc, but we’ll see if Sony decides to give the game a proper fit somewhere as part of this great collection set to land on October 23 (October 24 in Europe).  Between this and the massive God of War Saga, Sony is certainly making sure its main franchises remain in the minds (and libraries) of gamers who can’t get enough of them…
