This game is awesome! Dont bother buying something else. Elder scroll 4 Oblivion is similar to Morrowind with graphics

Simply the best game since ... Morrowind. A bit less open and a bit more directive in quest, it's a good thing if you dont want to play for more then 100 hour. But there is still the same open land, dungeons and caves like Morrowind. They add a fast travel fonction that's easy and really usefull. There are the guild you could join the fighter guild, the mage guild, the darkbrother hood (assasins) and finally the thief guild. Lots of side quests to do along the way of the main quest. Lot's of caracter details in the level up and a lot of planification to optimise the caracter. Loads of plant to collect to make potions and poisons.
It's really a game to try. It's easy to get in the game and easy to stay in.
