I'm sure someone will come by and get you situated into the proper forum. I'm also sure someone can help you with your problem. But it would help greatly to know what systems you have available, what games you have already played, and what kind of games you enjoy in general. Price might be an issue as well.
I've seen the light and can say Shin Megami Tensei, take your pick. And Etrian Odyssey, The Dark Spire; anything by Atlus.
By the looks of seo's avatar, it seems he/she wants to know he/she is moving up in the world. I suggest the girlfriend experience. Buy a prostitute and get laid (or whatever you want it to do). The only game I'm thinking of is GTA: IV at the moment. It's not too old and not new. It's just right in you aisle. What if you already played the game? Like Slicky mentioned, it's hard to suggest games to you if we don't know you. That being said, I'll wait for you to post more info.
I don't think he is coming back. What is all this Slicky business? Calling me greasy?! Don't try to deny it, the T key is too far away from the L for that to be a simple typo.
