Oblivion starts out as almost all Bethesda games do. SUPRRISE! Your a prisoner. The game then unfolds into a tutorial level on navigating the new found tunnels of the prison in order to escape from the sewers. From there the story is up to you. You can either follow the Emperors order's and go to a man called Jaufree, or you can ignore him entirely and go do whatever the hell you want. There are about 5 main quest paths in the game, each of them belonging to a different guild or faction. You can complete all of these if you want but doing so is going to eat out a large chunk of your life. I'm fine with it if you are. The main story quest in oblivion wasn't anything too special for me, but some of the sidequest and the other factions quests were just simply amazing.
These just get plain annoying after a while.
Oblivion looked pretty damn good when it first came out, but sadly age hasn't done it any justice. They tried to use a more realistic art style, and it worked out, until other games did it bigger and better. Oblivion isn't too bad to look at but there are some things that will just make you cringe, particularly the faces. If you play it on PC you have the option to fix all this by downloading face mods, texture packs, and other graphical enhancements. It's sort of necessary to play on PC in my opinion, mainly because the modding community is so huge, and there are so many great mods out there.
Get away from me you monster!
Sounds is another thing that oblivion could have worked on. It all sounds good in the first hour of play. But past that and you'll have heard every sound the game has to offer. The music is almost the same everywhere you go and there is only about 2 battle songs that play throughout the entire game. This got incredibly annoying to me and thankfully there were a lot of mods to fix my problem.
Gameplay in this game is, for the most part, entertaining. It's basically set up as an FPS with swords, bows, and magic. It sounds good on paper, and works very good in the beginning, but as you advance in levels it gets pretty frustrating slashing your enemy 50+ times with your badass sword of doom, and only take half of his health away. Some of the spells have problems too, they move very slowly so casting them at range is almost impossible, Thankfully again, the modding community saves the day with some excellent mods that fix nearly everything about the game.
With mods you can be anyone you want to be.
Oblivion is a pretty good game, if you download the good mods for it. If you don't have a decent PC to play this on i would suggest shying away from it unless you can just look past all the bad parts. You'll get at least forty hours out of this game, and at the price it is now, it's a pretty decent value.
