Obviously the 360. I never actually enjoyed using a PS3.
For a few reasons, but mainly due to the controller;
The L and R triggers are too far back.
The controller is too small.
The charger lead, that measures about two centimetres.
Ten hour updates and installs at the beggining of every game you play.
DLC's arriving two to three months late.
Etc...
Level 75 Khajit (Can't spell it)
Dawnguard, Hearthfire and Dragonborn DLC's.
Fully Deadric armour and weapons.
Mainly use a bow.
Been playing Skyrim for a couple of years now. Probably the best game I've ever played.
Completed factions;
Companions
Empire
Winterhold college
Thieves guild
Dawnguard
Probably a ton more, but my brain isn't powerful enough.
