Multiplayer
Bethesda's reasoning is sound. Time spent creating multiplayer is time lost on single player. Yeah, I'd love to be able to have my friends drop in on my game, that would be amazing. But hell, Bethesda's games are unpolished enough as they are, spending less time on that isn't a good idea.
DLC
Can we stop complaining about DLC? So what if there's plans for DLC already? There will always be ideas that don't make it into the game because they don't have the budget or time or whatever, and DLC is a way for publishers to deliver the content they wanted, after they don't have the pressure of releasing the game, or the sales bolster their budget.
Epic Scope
Morrowind felt large, without feeling empty. At least it did to me. Yeah, Oblivion's generated meadows made travel very boring, but Morrowind was a unique map, full of ruins and all sorts of other shit to explore. I spend hours just wandering the wilds of Vvardenfell. Maybe Skyrim will be the same. And why is it in one paragraph they complain that the size of Oblivion made it seem empty in places, and then to sum up they say Skyrim should have been bigger?
Combat
Bethesda's games were never built on combat itself. You level up, increase in strength, equip yourself with better weapons, armour and spells. That's why Morrowind was basically a dice roll system. Of course Dark Souls will have better combat, it has to have a tight combat system to provide challenge without artificial difficulty.
Dragons
Seriously? The dragons are better? Don't you think that's trying too hard? Especially since all you have to go on is footage right now, and it's kind of cheating to say the dragon fights will be better when you've already made combat part of your argument.
Just to make it clear, I'm playing devil's advocate here, but I do think some of the arguments are ridiculous. That said, if I can get a PS3, I shall be buying Dark Souls. It sounds like a great game.
