30% off Crysis, 30% off Dead Space, If you pre-order Sim City you get a £15 token off your next game. not sure if this can be used to get one of the other discounted games, but you may be able to. If that's the case you'd be able to pourchase Dead space 3 for £12.99 (usual price from Origin is £39.99), or you could get Crysis 3 for the same price with a similar saving.
I highly recommend Crysis 3. not purchased Dead space 3 yet. Still not finished Dead Space 2.
