I think dishonoured is excellent, good re playability with at least two distinct ways to complete every task (stealth or kill kill kill). Definitely worth a purchase (especially if you can find a deal )
You've missed their 20% off promotion unfortunately. Although they regularly do that sort of thing (or have been recently, so might be worth waiting?).
They would supply the steam code though so you would be gaming faster!
Can't wait to get my new computer and start playing games like this. Still a while yet though. This waiting game is no good, I keep nearly changing my mind on my specs.
