Well with 50% off I'd get the most expensive thing possible, is this the 50% off voucher if you buy DS 2? I decided to do that, and used a cokezone £5 off because I couldn't be bothered waiting for a cheaper delivery offline, the cheapest places have awful delivery and the decent places with next day del weren't any cheaper.
I thought it was a decent deal but have since realised it can't be used on a pre-order, and due to the shockingly poor Oct-Feb game release period for the PC, theres really very little on EA store thats worth buying, the new games I wanted to get are all on pre-order, and the 50% off is only up till late Feb 18th, so theres really nothing coming out till after then.
Most of the other stuff you'd want to buy is so cheap 50% off is a complete waste on them,
EA downloader isn't close to pants, its basic, but thats all it needs, they've added the store which is a shame as frankly I liked it better than steam because it was a downloader only, you could launch games through it, if you wanted, but theres no requirement to have it open to play games at all. Not a fan of how much junk Steam has now, nor that you have to have it open and wait for it to load and connect/try connecting before opening a game.
