yeah, like...its his theory... nyah, nyah, nyah... because he wrote it on a blog... nyah, nyah, nyah...
Try to successfully complete–oh, say, Fallout 2–by role-playing a scientist. Go ahead. Roll up a new character and put all of her points into the Science skill. No save scumming, now. Or how about a scientist-doctor? Maybe one who loves hiking. Stick all your points in Science, Doctor and Outdoorsman. See how well that works out.
So fail and try for something a bit more adapted to the game's hostile environment. Beat the game, and then try the hiking scientist again now that you know some of the pitfalls and setbacks to your build. I mean, seriously, why should the dev be tasked with the impossible mission of keeping the player from screwing himself over by bad decisions? It's not impossible to beat F2 as a hiking scientist/doctor, but it's naturally a lot harder than as a charismatic gunslinger, and it's harder in a way that you'll notice instantly. If you beat 90% of the game using SCIENCE! and got buttfucked by Horrigan on your way out, I could understand the complaint.
Honestly, I'm not sure I like his proposed "solution" to the "problem", forcing common sense on the player by dividing up skills into "useful" and "flavor" and creating two pools of points from which to level up. For one thing, it means you're forced to waste points on skills which you may have no interest in or simply don't fit your character build. Secondly, you're forced to create characters that are realistically viable, i.e you won't have characters that rely on followers or cheesing the game to win. Thirdly, it undermines the importance of a well-planned and thought out skill distribution, in the same way skill trees or classes do by limiting the nonsense you're able to accomplish as you level up.
I like the idea of people failing because they unwittingly throw everything they got at a less viable skill, all it does is demonstrate, something that should be obvious, that the world into which the player is thrown simply isn't fit for a pure scientist or a toaster repairman, unless, of course, he makes exactly the right decisions. All this amounts to is a safety-net for dumdums at the cost of everybody else's freedom -- i.e the usual decline doctrine.
