A reasonable amount of skill books adds flavor to the game, as is the case with New Vegas. It's fun to hunt them, manage your skill levels so you don't waste points.
Now when you got 25 skill books per skill, you say "aw [censored] it there's damn too many anyway".
I know they're optional. But a pistol that shoots 1000 damage lasers would be optional too. See where I'm getting?
Okay, all kidding aside --
There are unquestionably items in both F3 & F:NV that can svck out the challenge. I won't dispute that for a second. Have you played Dead Money? There's an item at the end of that that
kills much of the challenge in F:NV.
I think the developers of both games had an eye toward pleasing both the casual player and the hardcoe gamer. Very few players in my acquaintance play the hell out games like I do. That's why there are seemingly-silly perks like the ones that grant instant levels or extra experience. Most people (those b*st*rds with a real life...) are not going to spend 50+ hours with a game; they want to play through on a direct path and the games account for that.
We few who fritter away our existence fiddling with every possible option on games like this have to exercise restraint, is all. It's an unfortunate consequence of obsessive play that eventually we get so high level that the challenge (which I would argue is more satisfying than just having fun) goes away. I deliberately did a Vegas character who, with a couple exceptions, brought skill point and SPECIAL perks exclusively. He was just as effective as a character with tons of combat perks. It's a consequence of being high level and
not having the option to refuse perks or skill points.
I find it good fun to be the demigod for a while but it quickly wears thin. I'm playing one now. He's about to be retired until some more DLCs come out, because absolutely nothing is a challenge any more. My character built for sneak, explosives, science and energy weapons now just openly strolls around the wastes casually one-shotting cazadors and deathclaws. Fun for a while...
So yeah, I do understand what you're saying. I don't totally disagree with you. But options are options. I don't have a beef with skill books or superweapons because I don't have to use them. Not having a choice about maxing out unwanted skills is another thing, something I hope the next fallout takes into account.
