yeah that wouldn't work too well with science or lockpicking. The game was designed around the 100 limit. I just think it would be a bad idea to raise the level cap without raising point caps also. It probably can't be done and that's fine. The game is balanced the way it is now. I do hope they have a higher skill point/level cap in future fallout games.
Aye, although if they do put in higher skill caps I think they would probably add in conditional modifiers likes of a range penalty for ranged weapons, lock condition/sophistication for lockpicking, how easy/difficult and how straightforward or esoteric something is to repair, for hacking whether the computer has any security programming running and how crude/sophisticated they are could all affect how easy or hard it is to do something.
To give an example with hacking depending on the sophistication of the computer that could affect the difficulty in hacking it and also on top of that you could also have security software to make it more difficult again with the modifier varying depending on the sophistication or even how esoteric the security software is. So you could have a situation where you have someone's home terminal (relatively easy to hack) but it's also protected by some pretty heavy security software (very difficult to hack) which equates to a required science skill of let us say 75. For a second example you could have a military computer (very difficult to hack) protected by extremely heavy security software (extremely diffucult to hack) which equates to a required science skill of let us say 175.
For a lockpicking example you could have hmm a basic lock (very easy to pick) but it is in poor condition (hard to pick due to the parts being difficult to move) which requires 50 lockpicking and again for another example a bank vault door (extremely difficult to pick/unlock) with additional security measures (extremely difficult to bypass) which would require let us say a lockpicking of 200 to get past.
I could add more examples but I think those two show enough of what I'm trying to say.
