Yeah, Thief is a decent game at that price - just don't expect it to be as good as the old Thief games, if you ever played them, back in the day. This one's way too linear.
Haven't bought anything physical in the Black Friday sales this year, but I did add a few games to my xbox library. Picked up The Escapists last week, and also got Rare Replay this weekend. RR has been as cheap as £9.99 for a physical copy, but I was holding out for a decent price on digital - so was happy to pay £12.99 for it.
Haven't played them, yet - nor have I played any of the last few months' GWGs - I've been busy playing COD Blops 3. Pretty good fun, though as always I'm not very good at it and my K/D ratio is appalling. It's getting a bit better now that I'm at a high level - so have access to better weapons and equipment. I was always a fan of the claymores and bouncing betties in the earlier instalments, and the futuristic variant "trip mines" are keeping my stats reasonable now - I get more kills with them than with my guns (I'm mainly sprinting around dual-wielding pistols). With the trip mines it's all about the positioning. In Search & Destroy (the only game mode I ever play) you soon know good places to put them, but there's always new places to learn.
Sent you a message on the xbox yesterday, btw, Kieron - not sure if you've seen it.
