I assume most of us would do our best to achieve all of the Skill Points in each Ratchet and Clank game. In your own opinion, what do you think are the most difficult Skill Points to achieve in each Ratchet and Clank title?
In the first Ratchet and Clank, "Tricky" and "Alien Invasion" is probably the most difficult in the game. For "Tricky", you pretty much need to know the Twisty McMarx trick to pull off this skill point perfectly. As for "Alien Invasion", using the visibomb to take down the Blarg Ships is were you need to use the weapon at the right spot and good aiming to get this particular skill point.
In Going Commando, I would have to say "Nano to the Max" just because the Nano Tube in planet Dobbo is probably the most difficult one to get in the game. I've managed to obtain it, but it requires a lot of practice to get it for that particular skill point.
In Up Your Arsenal, There weren't too many difficult skill points in the game but I think the most challenging ones would have to be "Stay Squeaky Clean" or any of the "Set a New Record for Qwark" skill points.
In Tools of Destruction, I think any Skill Points that involves any ship battles such as Verigris Black Hole and Rakar Star Cluster were the most challenging (or even impossible) ones to complete just because the controls were just hectic when it comes to shooting enemies down or trying not to get yourself hurt.
I am not sure what is/are the most difficult Skill Point(s) to achieve in A Crack in Time, so I may have to go to it and see which ones are the most challenging in that game in particular. Same goes with Ratchet: Deadlocked too.
