I received the game yesterday, so i only manage to play Ratchet and clank: Up your arsenal (which is btw my favorite game, along with God of war, for the ps2). Let me tell you something... It is still as fun as i played 5 years ago! I'm so glad they did a hd of this game, because the current R&C for the ps3 are nothing compared to this classic. (Dont get me wrong they are fantastic, but it does not have the same impact as Up your Arsenal).
If you havent played any R&C, this is your chance to buy this game. It combines the first 3 r&c on the ps2: Ratchet and clank, Ratchet and Clank: commando and Ratchet & Clank: Up your arsenal. The Ratchet & Clank series is like a mix of platformer and 3rd person shooter type of game, with lovely characters and funny setting. I havent played the first two but I going edit this later when I played, but for now, I can tell you that Ratchet and clank is addicting!!, leveling your weapons, and buying weapons, collecting bolts (money), finding hidden treasures make this game amazing ! Once you start playing it is Very hard to put it down, you want to see what is going to happen next...
So for $30 dollar, I highly recommend to buy this game to anyone who have a ps3,no matter if you played on the ps2 6 years ago or even if you dont like fluffly characters, this game is extremely fun. Heck, I would have payed $30 dolars only for Up you arsenal. Also this game have trophy which makes it more addicting!
Edit: I played the other 2 ratchet, and to be honest.. the first Ratchet is... terrible! controls are bad, ratchet is so hard to move around and weapons does not upgrade.. So if you are not a fan of R&C and you are no interested in the story, you wont be able to play the first cause is terrible. Luckily the second one is so much better, from there the upgrading weapon system is available and ratchet move as easy as it should be. So aside from the first ratchet, the collection is awesome!! Still in love with the third R&C: Up your arsenal, it is a masterpiece, the best in the series. It is obvious how much R&C have improved from the first one!
