Wait...what? I played Oblivion. Are you sure you did?
Let's be objective here-
Combat: Different system than Oblivion except that you wear weapons and armor. Different proficiency system, addition of perks. Elimination of 'power attacks' by for instance attacking while moving backward to cause an enemy to be knocked down or strafing and attacking, disarming the opponent. No more separate cuirass and greaves. No blade skill. No blunt skill. Replaced by one hand and two hand. Addition of finishing moves.
This is not an improvement from Oblivion, it's a different system
Iventory: No 'paper doll'. Odd UI, but similar to Oblivion in the manner that it lets you look at an Inventory at least. Little things have changed, like how books are read
This is not an improvement as it uses an oddly designed UI and works differently than Oblivion's. Different type of inventory
magic: No more 'one shot' spells for everything- now you hold the button down and continue that flame. Spells in either hand. Spells in both hands. Same spell in both hands. Nothing like Oblivion
This is not an improvement from Oblivion, it's a different system
Worldspace: Obviously created differently than Oblivion was
This is not an improvement from Oblivion, it's a different way of doing it
Interactions with NPCs: similar to Oblivion in that NPCs talk to you. Gone is the speechcraft mini-game. Instead, options for speaking are present. Sometimes with options you really shouldn't know
This is not an improvement from Oblivion, it's a different system
Shall I continue??? The game is different. Just like Oblivion was not 'an improvement' of Morrowind. It's different. Same genre, different way of designing the game
Dude, what you just said might be the Dumbest crap I ever read. You could say that about basically anything "its a different bleh so cant be compared" SURE AS HELL IT CAN! Wrong Wrong Wrong Wrong Wrong. Different ways of "doing it or that" can also be said to be BETTER, I could eat food through my nose, but I use my mouth, because its a BETTER WAY TO DO IT, at the same time its also DIFFERENT from using the NOSE. Moron..
OT: I liked Oblivion, but I like Skyrim aloooot more, I never tried Morrowind. I only need the bugs, glitches, random crashes and the higher FPS = insane vertical mouse speed bs. If that were taken care of Skyrim would be the closest thing to a Perfect game Ive ever played.
