When I play oblivion for the first time, I thought it was a pretty nice game. However after playing over and over, and playing the other games like Fallout 3 and Fallout: New Vegas, I find the game and the engine a bit boring now and tired of the engine and the looks. I like oblivion due to the combat system, how you can properly hit the enemy without a judge of skill like in morrowind. I can kill enemies and not get killed by a damn meager animal like a damn crawler in Morrowind. The Storyline in the game was ok, but not that great. It was a bit lengthy, but not that much lengthy to last 2 weeks playing though the whole storyline, even when cheating. Most of the places that I've been to are mostly scripted or suppose to belong to a script of a quest, which sometimes I dislike when I want to explore a dungeon without any influence with a quest to level up, get new gear from chest, and other things but now I kinda felt bored after acquiring the toughest armor out there, and felt dissatisfied how there is not enough verity in the weapons.
Since skyrim have been announced, I would be happy, but after playing though Oblivion, Morrowind, Daggerfall, Fallout 3, and Fallout: New Vegas, I know that I would suffer from a lack of verity of items, the storyline can probably be beaten within 3 days, it might be buggy as hell, nice shiny new graphics but it will wear out within time. What else is there to expect from the repetitive Bethesda Studios?
