Fallout NV or Oblivion

In the past year I have not played a single Elder Scrolls game *gasp*, but I have played plenty of Fallout 3 GOTY and Fallout New Vegas.
I am starting to become bored with NV ever since I completed the main quest and a lot of the side ones on my level 30 character. I haven't bought Dead Money yet but I do intend to pick up NV once all the DLC is released and I can get it all at once.
 
So should I trade in New Vegas and pick up Oblivion GOTY?
I really miss the whole fantasy magical world and often find myself thinking of a new character I have never tried before. 
(Stealthy with some skill in Magic and archery)  
The last time I played Oblivion I was in middle school and didn't understand the concept of an RPG so I would like to try again with my experience I have obtained from Fallout.
So should I?
 I can't make decisions for myself so I ask complete strangers.
FYI I will be playing on a PS3 since I don't own a PC that could run Oblivion.

wait til Skyrim, tho Oblivion should be cheap as chips now and is definitely worth a look. I am thinking of getting back into it simply because I have never finished it, but have somehow had two 20 hr playthroughs.

Get Oblivion and sell NV; NV was a terrible game, IMO. Though, I'd just wait till Skyrim at this point.

Morrowind.

I dislike both of those games. I liked Fallout 3 though.

i don't like trading in games for the sole reason that i feel like i may go back and play it.... and now i have like 70+ 360 games.... i don't know whether to be happy or not.  
 
Oh and Oblivion is one of my favorite games, but i haven't played New Vegas. Just go buy Oblivion, it can't be that expensive.

" Morrowind. "

New Vegas, or wait to Skyrim.

I like New Vegas but I would go with oblivion goty, you can get it for $20 now and its an awesome time blowing game. 

New Vegas has decent writing, a first in Bethesda games.

fallout 3 == excellent concept - heavily flawed.  
oblivion == excellent concept - heavily flawed.  
 
i'd play oblivion

Thats a hard question

" Morrowind. "

Get both,if you can't still get both of them.
But seriously,its Medieval fantasy vs Post apocalypse,the latter always being the winner in my opinion. Its up to you though.
