Minimul graphic engine upgrade? I don't know what trailers or screenshots you've seen but the graphics are hardly anything more than justa minimal upgrade.
ack-ack
Im sorry but:
http://www.youtube.com/watch?v=ItQOo28Kd_UThe graphics are upgraded from Oblivion's when it comes to their glossiness and crisp image quality which is completely expected of any game made today. Oblivion is what? 5 or 6 years old now.
Pay attention to the actual graphic objects in the game. The houses are the same, the NPCs use the same models (their skins are updated to new graphics), the voices are the same audio/acting quality as those found in oblivion/fallout2/etc: bland, empty, scripted.
Honestly, I think all they did was recycle the oblivion engine, upped its graphics crispness and 'modded' oblivion into skyrim. Thats how it looks and feels like.
Even the damn gameplay is the same. The same retarded raise-hand, glow-hand, lame spell cast animation.
I expected a new game not a rehash of an old one.
