But ppl that got Oblivion 1-2 years after it came out may feel that skyrim feels empty but that's because of all the amazing mods the community made, give it the same time (or less) and i believe skyrim will pommel oblivion to the ground.
My complaints with skyrim is the magic system, it's alot better than olivion but it feels unfinished, lacks in spells, there's no combo with different spells (for ex. a fire and an ice spell to create a scolding fog), companions are useful but bland, marriage system is dumb (where's the romance?).
I can hardly wait to see what the community will make of this game when the kit comes out, there where some truely amazing mods in oblivion and i have a feeling this game will get a bigger boost than oblivion could.
