Got no joy looking for a Day One at the other branch of Game, but had a chat with one of the lads there.
They announced a few days back that they'd be giving £40 trade in on COD, Battlefield, or FIFA (ps3 or xb360) when traded in against ps4 or xb1 versions of the same game - which is pretty similar to the deal Activision announced on COD a while back, so it's decent but nothing outstanding. But he also advised that the £40 trade-in offer applies to their xb1-cod bundles. That's piqued my interest, as it's £460 for that bundle (regular version of the game, not the rip off Premium one). It's not a Day One, so almost certainly no FIFA included*, and the COD you get is digital, but you're saving £20 on buying the console and game separately.
£20 outlay now as deposit on the bundle. Buy COD early Nov. Hand over £400 plus the xb360 copy of COD in late Nov and walk away with the console & game. Tempting...
*He said FIFA definitely isn't included with preorders that aren't "Day One", which ties in with the latest I've heard, but contradicts earlier info from MS. I do wonder if there'll be a backlash if FIFA isn't included with all preorders, which might result in MS giving the game or compo to preorders who didn't get Day One. There's no basis for that assumption, though. It's just a shot in the dark...
