Okay, so I just really discovered this board. I used to love the ratchet games...finally got the collection.
Problem is, I am not enjoying the 1st ratchet game. I went straight into the 2nd one (going commando). So much better to strafe
Yeah, the first game is pretty outdated. They really hit their stride with the core mechanics with the second game and have just been refining on that ever since.
UYA is also my favorite R&C game, though I would say A Crack in Time is probably the best of the series.
Drek is probably the toughest final boss in the series. You run out of resources too easily. But if you get the PDA in the secret area of the stormy city level, you can replenish your ammo mid-battle and that might be a cheaper route than the claw.
