Ratchet & Clank Future: Tools of Destruction

For some reason at the moment a lot of people consider this game just another good R&C but for me this title can truly fight for the first place. This game has probably the second best story in the franchise, really good villains ( like Slag and Tachyon) and an outstanding world building with a lot of lore. The gameplay feels like an updated version of that masterpiece of gameplay that we see on Up your arsenal and Deadlocked, with a really good level design of the planets that reminds a lot of the level design that we see in the first two main entries in the franchise. An amazing soundtrack and incredible graphichs for the time can really explain you why this was considered a system seller game at the time.
