Without giving us anything else to go on, I recommend Googling 'games'.
Get Mount & Blade: Warband. You're welcome

I have it. And it is awful...
NO MMOS!
Didn't you make a thread like this like, a month ago?
Anyway, not many games out there that seem so amazing to get interested in. At least, not for me. I'm rather picky with games.

What do your interests include?
Nope. And how the hell do you remember my thread history?
That's not funny.
Are you looking for a more epic answer than, "post count +1" or "too lazy?"

@OP: You really need to list more specifically what you're looking for... A single-player game? Multi-player? RPG? Shooter? Action? Mario?
I suggest you pick up Dark Souls, (or demon's souls if you have a PS3.)
I've heard how difficult that game is. I will just rage way too easy.
No need, I already have the perfect solution. Given how the OP's PC has problems running Mount and Blade and Oblivion, the Witcher games aren't an option. So, the obvious choice left is to get Vampire: The Masquerade - Bloodlines.
I don't have PC problems. Just it isn't a gaming PC, so it only runs slightly older games such as Mount & Blade and Oblivion (even them not too great). Plus, I don't like Witcher 2.
Why do people make these posts? Just research and try demos to see what you might like.
