Which of theses games should i get ?

I searched on gamespot and made a list of games which i should get. Here it goes :

-Singularity

-Dragon age origins

-Mafia 2

-Resident Evil 5

Out of the list, i've only played Dragon Age Origins & Resident Evil 5.

I would go with Dragon Age Origins.

dragon age is a pretty awesome game, and you will be get a lot of hours out of it. If you can wait two days Civ 5 is coming on tuesday and will give you hundreds of hours of enjoyment or steal hundreds of hours from your life, whichever way you want to look at it.

Out of these, I haven't played Mafia 2.

Dragon Age is a pretty good and long game.

Singularity is rather short, but it's a decent FPS.

RE5...I have yet to complete that since I got bored with it.

I got singualrity at nearly full price, Its got about 7-9 hours of well polished singleplayer. I completed it on hard first time, if you like Half Life and Bioshock get it, Its a good old classic fun FPS. I couldnt get the multiplayer to work but its worth at least 2 play throughs.

I havnt played the other games, although I enjoyed the Mafia 2 demo.
