Which of these games should I buy next?

Question

I asked this question before and all the answers suggested games not on my list, so let me be clear. DO NOT SUGGEST NAMES NOT ON MY LIST.

These are the games that I already own:
Little Big Planet
Batman: Arkham Asylum
Uncharted: Drake's Fortune
Mass Effect 2
LEGO Batman: The Video Game

These are the games I'm considering buying next:
L.A. Noire
Heavy Rain
Batman: Arkham City
The Elder Scrolls IV: Oblivion
Final Fantasy XIII

Please don't just say "All of them" because while I am going to buy all of them eventually, I can only afford to buy one game a month since I'm saving up for a trip to Phoenix.

Basically, I'm having trouble figuring out whether I should buy Arkham City, a game I know I will love and have been wanting since before I even bought a Playstation, but is pretty much just more of the same stuff you get in Arkham Asylum. Or if I should buy something else since I've been trying to try out a bunch of different kind of games so I can see what I like and also have a vast variety to choose from if I'm not in the mood for a certain type of game. And even then, I don't know which of the above games I would get, so that's why I'm asking you. Here are the qualities I'm looking for in a game:
-Long OR has replay value (or both)
-Interesting storyline
-Not too similar to the games I already have
They don't have the have all these qualities. If a game is different from the games I have and has an amazing storyline, I'll still consider buying it next, even if it's the sort of thing you can really only enjoy playing once.

Answer 1

I'd say give Final Fantasy XIII a chance, especially since it's very cheap now.

Answer 2

Well since you already played arkham asylum i would suggest you to buy arkham city cause it's pretty aweome, and you can now buy with all the dlc for a lower price.

Answer 3

Oblivion, 100%.

Now that Skyrim is out, its cheaper.

There's many different story lines with the guilds you choose, also.

The graphics are great and it is overall a VERY fun game.

Answer 4

not a game of them, but it should be butter than all..



I think you should buy Battlefield 3 and everything will be different in your video game world ! :)
