What should I buy?

Dead Island. I had a lot of fun with that game.

I'd say Killing Floor.
Dead Island/Riptide are both good games, but get very repetitive, and boring alone.
SR2 isn't bad, but I still think KF is better.

Or...you could buy 3 TF2 keys and trade that for the Saints Row Franchise Pack, or if you don't have quite enough for 3 keys. Buy 2 for the Dead Island Collection. Or if you're super strapped for cash, 1 key for Killing Floor is always an option.

Well, you still gotta decide which franchise you want, but at least now you don't have to choose between games within the same series.

EDIT: Also, I'd recommend grabbing Metro 2033.

Killing Floor !

Batman Arkham Origins on GMG

Killing Floor would be my ultimate choice

buy 2 tf2 keys and trade with someone for dead island collection,thats what i did

Sorry for hijacking but I don't want to create a new thread so I was gonna ask similar question.
GMG Credit 7$. Darksiders 2 4.99$ or Batman Arkham City 4.99$.
I have Darksiders 1 unplayed and no Batman games at all. Or should I avoid this purchases and wait for another game?

Saints Row 2

Killing Floor for more hrs to play but in Multiplayer. Dead island series (either or) is quite good for Single player though. Cant say anything abt SR2

Killing Floor.

Drugs. Trust me.

Save your money. Buy Saints Row the Third or SR4 because SR2 is poorly optimized.

Thank you all, I bought Dead Island Franchise Pack for 2 TF2 keys. Because I have Saints Row: The Third (Similiar SR2) and Left 4 Dead (Similiar KF). I think I don't have anything like Dead Island. :)

You want multiplayer? Killing Floor.
You want singleplayer? Dead Island.
