Which mechanics? I think it resembles Oblivion much more so than the old FO's. And yes, the perks are now also in Skyrim it seems (280 of them).
The entire SPECIAL system, which is pretty much entirely from Fallout.
In terms of gameplay, I think it resembles what would happen to Fallout if you streamlined gameplay and made it first person.
Like always i'm not expecting a 100% perfect game out of the box, just like all their other games i'm gonna play it on PC and fully modded (I'll probably wait a few months for mods). I needed far less mods to enjoy FO3 than to enjoy Oblivion though. Better combat, better animations, just those fixes will make it a lot better than Oblivion (which wasnt a BAD game, i've spent hundreds of hours with it to be completely honest, i love to pick on it anyways though
).
I don't expect anything, really - except something resembling what has come before.
I prefer to see something released, before I get really excited - unless I have something tangible to tell me what it's going to be.
So far, we have too little information for me to get excited.
I do know, though, that I used to get really excited about TES games - from Daggerfall to Oblivion - and they've all been hugely disappointing when compared to the hype.
So, I don't really want to get caught up in hype - and I want to try to learn from the past.
But, if you loved Morrowind/Oblivion - I can certainly understand the excitement. I'm sure you'll get something resembling those games.
I liked both games after mods - but they both had severe flaws. But it took me a few weeks with each of them, before realising how flawed they were - as they were so huge.
I'm actually looking forward to a similar experience - and if Skyrim is equally flawed - it will still take me a week or so of being excited and entertained. That's kinda what I'm expecting - and I prefer to be pleasantly surprised if it turns out great.
