Having played and enjoyed every single Elder Scrolls game since Arena, I will definitely be buying this game - regardless of the hype. In fact, I'm deliberately avoiding reading (or watching) anything about Skyrim until it comes out.
Oblivion was (and still is) an astounding game, slightly let down by silly story/quest paradoxes, a few bugs (actually hundreds of bugs), and a lame end-of-game bad guy (Mehrunes Dagon was little more than a statue, which was a pity). That said, Skyrim surely can't fail to build on the best elements of Oblivion (the incredible world in which you explore; the excellent graphics; the incredible atmosphere; the stunning music; the interesting levelling system; the incredible depth, and the cool interface and controls) and Fallout 3 (the excellent combat system; great plotlines and explosive situations, and dark humour).
I'm hoping that the combat is a mix of Oblivion and Fallout 3 - real-time and turn-based (a la VATS), though if it's just real-time I won't be complaining. And I'm also hoping that the world is more realistic than Morrowind.
I hope they improve the map system from Oblivion, and retain the deep alchemy and spell creation systems. As well as the brilliant side quests. Instead of vampirism, why not try lycanthropy this time?
Oblivion had balls; it had grit; it was a game for adults and not kids, which made it for me. I'm crossing my fingers that Skyrim continues that trend.
Bring it the fuck on.
