I want to get a new PS3 game but what should I get (read description)?

you could try the elder scrolls oblivion game of the year or borderlands,both are very large open games with lots to do.i see you played fallout 3,most people who have played fallout 3 enjoyed playing oblivion and vice versa. you can get many,many hours of game play out of oblivion if you try doing all there is to do.borderlands was just an all out blast to play,there are so many different guns its crazy.there are over 100 different quests that you can do,main and side,there are 30+ different areas to open up and explore and you kill every thing in sight.hope this helps.have fun gaming.
