Here is something I wish the game were clearer about. A skill's level can't be more than its governing attribute's level. E.g. if your reflex attribute is N, then your handgun skill can't be more than N. So it's better to start off an attribute at a high enough level. The game doesn't really tell you this. If you already capped your handgun level, it will be stuck at 100% and you will lose any ensuing handgun XP until you put another point into reflex again. You don't get attribute points very often, and yet some skills don't take long to level up. Thus, it is easy for your skill levels to be capped by your attribute levels, and I'm not sure if this is a good system. You can still use a capped skill, but you won't be rewarded and you are therefore discouraged from doing so.

I think the system encourages experimentation, since it gets you to use other skills you haven't leveled up yet.

Not to mention all the other skills they haven't implemented yet.

I like it.

Gives me a reason to try all that random crap I'm picking up instead of just going for the biggest damage number gun I find and sticking with it permanently.

It's how I found out light machine guns are utterly terrible outside point blank range.
It's also how I found out that smart weapons kind of suck if you want to be precise.
It's also how I found out melee weapons are actually viable against gunmen.

You mean "forcing" you to experiment? A game of this kind usually doesn't force you into anything. If you want to beat Fallout 4 with only pistols or only melee, you can. I like to try different weapons too, but ON MY TERMS, instead of the game deciding when I should do so.

Oh come on!
It doesn't force you to do anything.

You choose to get that stuff or lose out on the benefits, but you can play through the entire game with just pistols if you want to.

The two cancel each other out. If a skill is quick to raise, then it'll shoot up fairly quickly after adding a point, no? It's not like you have limited opportunities to increase those skills (and to be honest, it's not like there's much point given the rather paltry rewards for doing so).

Exactly remember when games were about discovering play elements through mistakes, Hand holding console users have been so detrimental to gaming making titles so dumbed down.
