Very well. Weird, but whatever. To each his own. In video games, people generally record and talk about recording important things. So you can see where I would not have guessed that you'd record and talk about recording unimportant things.
No. My brother is far from "way too good". He clicked his way through three years of WoW and is currently clicking his way through SW:ToR. This is the sad part of the story. The first 30-50 hours of this game present zero challenge.So, using your own logic, you're bragging that your brother is in a way too good to play 25 more hours to get to a challenging point and that everyone else should be exactly like him.
Note that I'm quite happy with the game after that point. So this is not a "rawr, I hate D3" post.
A few moments of looking would have given you hundreds or thousands of posts on these forums and others of people talking about how Normal and Nightmare present no challenge.A game's difficulty is entirely relative to the person playing it, I'm not having that much difficulty with nightmare, with the exception of elite Sand Wasp packs taking a long time to kill in coop. I didn't know much about the different difficulties, hence the thread asking what to do next, I wasn't sure if I should farm gear for nightmare or just jump in.
In even less time, you could have loaded up Diablo, clicked "Nightmare" and figured it out for yourself. In fact, following your logic of "a game's difficulty is entirely relative to the person playing it" (which I mostly agree with), that's the ONLY way to solve that particular riddle as no one here can tell you if it's too hard for you.
I can fully get behind people who come to the forums and say, "I tried difficulty X but had some issues. Here's what I used, what can I change?" But asking if you should try in the first place...? Useless. The answer is always going to be, "Yes. That's the whole point of the game."
