oblivion is one of my all time favorite games,I was excitied to play this game again and get the achievements all over again on the japanese 360.If you have played the elder scrolls oblivion on the U.S. 360 and you loved it then this should definitely be a buy for you.The one thing that was a little bit of a problem for me was that everything that is wrote down in the game is in japanese.I ran in to a problem on a few missions were i got stuck cause i didnt know were to go cause everything was in japanese,So what i did was have a guide for each mission after that it was no problem finishing the game.the dialogue in the game is in english, also every thing else in the game is the same as the U.S version of the game.you can definitely get 100+ hours out of this game with the main story,side quests and the dlc (which is included with the game).So if you have a japanese 360 you should pick this game up.
