[H] Red Alert 3: Uprising, Dead Space, Mirror's Edge and Origin keys [W] Some game.

Hi there, I have last Humble Bundle copy, but I would like to trade some games I already have.

I have for STEAM:
-- Mirrors Edge.
-- Dead Space 1.
-- Red Alert 3 : Uprising

By the way, I have some great codes for Origin:
-- BF3.
-- Sims 3 Starter Pack.
-- Populous.

Look my game list, im interested in other good game we can change.
I prefer changing all the codes at once.
